Abstract:
In order to Figure the common defect in large section special steel forging and find the solution, systematic study was carried out on hundreds of large section special steel forgings in a domestic famous steel mill. The steels included: low-carbon steel Q345D/E, medium-carbon steel 27SiMn, high-carbon steel GCr15SiMn, stainless steel 20Cr13. Both the amount and type of all the defect in the above steel were calculated and analyzed. The results showed that the common defects of the steel were slags, inclusions, loose (cavity) and inner cracks. The evolution of the cavity in the ingot during forging process was simulated by a numerical simulation software Deform-3D. The inner cracks in Q345D/E and 27SiMn initiated after A→F+P transformation The cracks in GCr15SiMn formed after the precipitation of net-like proeutectoid carbides. The cracks in 20Cr13 formed after the precipitation of net-like carbides. The internal cause of the cracks was relevant to composition segregation and internal stress in the forging. The external cause was connected with effect of slow cooling. Based on the above study, a set of new process was proposed and put into industrial application, with the result that the qualified ratio of flaw inspection in the above steel mill was improved from 20% to above 87%.

This study is an approach to investigate the viable impacts of screw manufacturing. At the same time, choose the suitable material and selected manufacturing process of screw by considering environmental aspects without sacrificing the economic aspect. It is important to the organisation to improve the environmental aspect. Therefore in this study, the decision making was focused on economic aspects to produce the synergy results between economic and environmental impact. The parameters involved were types of material and manufacturing process of screw which using the available data of environmental and production volume. The two different manufacturing approaches being evaluated were machining and forging process. The types of material concerned for forging process encompassed low carbon steel, alloy steel stainless steel, and aluminium alloy. On the other hand, for machining process, the material being considered in screw manufacturing were cast iron, low carbon steel, alloy steel, stainless steel and aluminium alloy. The information of environmental impacts that generated from SolidWorks Sustainability tool and screw production cost were calculate using Manufacturing cost model, both information was used in Analytic Hierarchy Process (AHP) analysis to obtain local priority of economic and environmental impacts. Then, the ranking of both global and local priorities from economic impact and environmental impacts had enabled the determination of appropriate material used for those selected screw manufacturing process. As result, low carbon steel was chosen for forging process whereas cast iron was excelled in machining process, at the same time, stainless steel was not suggested to be used in both two processes.

Abstract:
Multilayered forged steel plates, which combine the properties of diverse steel qualities, are referred to as Damascus steels. Since the 3rd century AD blades and weapons have been produced by the Damascus technique in Europe. In this work four different steel combinations were investigated. Combining Fe with carbon steel C60 resulted in a ferritic-pearlitic microstructure. By forging two heat-treatable steels C40 and C60 martensite with an inhomogeneous carbon distribution was formed. Combining Fe with an austenitic stainless steel showed ferrite and austenite with grain boundary carbides and segregation bands. The last combination of two cold working steels K110 and K600 led to a complex microstructure with martensite, retained austenite and two special types of carbides. After metallographic preparation and using of different etchants the various microstructures were characterized by light optical microscopy and confirmed by Vicker ́s microhardness measurements. Of high interest are the interfaces and the quality of the weld between the individual steel layers. In some regions oxidation and carbon diffusion were observed.

Abstract:
Friction welding is a solid-state welding process using heat generated through friction. Dissimilar materials can be joined properly with friction welding. This study is a continuation of the previous study and aimed to determine the interface structure occurred on stainless steel and carbon steel joints. Stainless steel 304 and mild carbon steel are joined with this method at 2000 rpm rotation for 15 seconds and forging time of 5 seconds with a pressure of 5 MPa. The results of a micro-observation using a scanning electron microscope show good bonding in the interface area. The carbon steel is more welded to the stainless steel in the periphery than in the center. The spectrum results of Energy Dispersive X-Ray of the interface show Fe, C and Cr elements content. This is what causes the strong welding bond.

This study is an approach to investigate the environmental impact of screw manufacturing and to choose suitable material for selected screw-making processes for the best performance with minimum environmental impact. The parameters involved were types of material and screw-making process using the environmental data available in Asia region. The two different manufacturing approaches being evaluated were machining and forging. The types of material considered were low carbon steel, stainless steel, titanium alloy and aluminium alloy. As for machining process, the materials being considered in screw manufacturing were low carbon steel, stainless steel, titanium alloy, aluminium alloy, magnesium alloy and cast iron. The information of environmental impact are generated by SolidWorks. Sustainability tool was used in the formation of pair-wise comparison matrices for Analytic Hierarchy Process (AHP). Then, the ranking of global priorities had enabled the determination of appropriate material to be used for those selected screw manufacturing process. As a result, aluminium alloy was found to give minimum environmental impact for forging process whereas cast iron was found to excel in machining process. At the same time, titanium alloy was not suggested to be used in either process.

Abstract:
AbstractImproved designs, mostly for lightweight component manufacturer, have been made for improvement of forging and heat-treatment techniques. Low temperature precipitation strengthening and resistance to austenite grain size coarsening at reheat temperature for forging have been property improvement technique in these microalloyed steels. Studies of peak strain and flow stress at 1123–1423 K have shown increase in peak strain, peak stress and increment in mean flow stress in austenite phases in presence of vanadium. Partial vanadium alloying (1 part V substitute for 2 parts Mo) by substituting molybdenum has improved hardenability properties of conventional steels. Ultrafine grained steels have shown strain hardening effects from severe deformation by equal channel angular pressing (ECAP) followed by annealing. The strain induced precipitation of nano-metric sizes have pinned dislocations for strain hardening. Estimation of remaining life for reactor components have been done by simulated experiments under similar conditions as the service exposure. Vanadium in ferritic stainless steel has shown competitive performance, e.g. chloride environment. This has shown equivalent effects like nickel. In welding of microalloyed steel inter-critical grain coarsened heat affected zone (IC GC HAZ) has martensite austenite (M-A) blisters to yield poorest toughness.

Abstract:
The presented work is dedicated to studying the forgeability of bimaterial cladded workpiece. Hot upsetting tests of cylindrical low carbon steel (C15) billets weld cladded (MIG) by stainless steel (SS316L) are experimentally and numerically studied. Upsetting tests with different upsetting ratios are performed in different tribology conditions at 1050°C which is within the better forgeability temperature range of both substrate and cladding materials[ ]. Slab model and finite-element simulation are conducted to parametrically study the potential forgeability of the bimaterial cladded workpiece. The viscoplastic law is adopted to model the friction at the die/billet interface. The friction condition at the die/billet interface has a great impact on the final material distribution, forging effort and cracking occurrence. With Latham and Cockcroft Criterion, the possibility and potential position of cracks could be predicted.

Abstract:
Superheavy forgings are increasingly used in the nuclear industry. The strain rate is extremely low during hot forging due to the huge size of the superheavy forging; in fact, the surface temperature of the forging decreases obviously during each deformation step. Hot-deformation behavior differs from that of isothermal deformation. In this study, 18Mn18Cr0.6N steel was selected as a model material. Hot-compression tests were conducted using a Gleeble 3800 simulator at a strain rate of 10−4 s−1 and continuous cooling rates of 0.0125 Ks−1 and 0.025 Ks−1. The microstructure was observed using electron backscatter diffraction analysis and transmission electron microscopy. The flow stress increased with increasing strain: the higher the cooling rate, the higher was the hardening rate. Continuous cooling inhibited dynamic recrystallization by delaying its nucleation. The subgrain/cell size increased linearly with increasing final temperature of deformation in the temperature range 1273 to 1448 K. An intense <001> texture formed in 0.8-strained specimens and the matrix exhibited a low Taylor factor orientation. Most dislocations were separately distributed in subgrains and did not entangle with each other or with the subgrain boundary. Dislocation arrays transferred easily through boundaries and dislocation accumulation at boundaries was weak. This study contributes to understanding the hot-forging process of superheavy forgings.

Abstract:
Additive manufacturing with multi-material design offers great possibilities for lightweight and function-integrated components. A process chain was developed in which hybrid steel–steel-components with high fatigue strength were produced. For this, a material combination of stainless powder material Rockit® (0.52 wt.% C, 0.9% Si, 14% Cr, 0.4% Mo, 1.8% Ni, 1.2% V, bal. Fe) cladded onto ASTM A572 mild steel by plasma arc powder deposition welding was investigated. Extensive material characterization has shown that defect-free claddings can be produced by carefully adjusting the welding process. With a tailored heat treatment strategy and machining of the semi-finished products, bearing washers for a thrust cylindrical roller bearing were produced. These washers showed a longer fatigue life than previously produced bearing washers with AISI 52100 bearing steel as cladding. It was also remarkable that the service life with the Rockit® cladding material was longer than that of conventional monolithic AISI 52100 washers. This was reached through a favourable microstructure with finely distributed vanadium and chromium carbides in a martensitic matrix as well as the presence of compressive residual stresses, which are largely retained even after testing. The potential for further enhancement of the cladding performance through Tailored Forming was investigated in compression and forging tests and was found to be limited due to low forming capacity of the material.

Abstract:
The possibility to produce stainless steel components at limited cost and characterized by elevated mechanical properties, has gained more importance in the last years. Nowadays, the cold and warm forging processes of carbon steels are widely used to form industrial parts due to their economic advantages, but there is still lack of extensive research on industrial process design and evaluation of the microstructural properties of cold-warm forged stainless steel parts. In the last few decades, the environment concerning the recent forging industry has been rapidly changed. Now, near-net-shape or net-shape manufacturing processes are becoming a useful practice in metal forming, resulting in saving material and energy. Many parts produced with machining can be manufactured at lower cost by cold and warm forging. Traditionally, forging design is carried out using mainly empirical guidelines, experience, and trial-and-error, which results in a long process development time and high production costs. In order to avoid this, in recent years, computer-aided simulation approaches have proved to be powerful tools to predict and analyze material deformation during a metal forming operation. There are now many commercial finite-element (FE) packages to simulate forging and bulk metalworking processes. To date, most have focussed on predicting the shape of the final product after simple or complex single- or multi-stage forming operations. On the other hand, other aspects are being included in these numerical models, such as an improved understanding of the constitutive material behaviour, friction and lubrication conditions, and the properties of the final product, in order to predict more complicated phenomena such as tool life prediction, ductile fracture and microstructure evaluation. The focus of this PhD thesis is the development of an innovative approach based on the design of integrated experimental procedures and modelling tools, in order to accurately re-design a range of industrial single-stage cold-warm forming processes to form stainless steel components and investigate the microstructural evolution of forged parts obtained at different forging temperatures. In addition, the design of a multi-stage cold forging process of a low-carbon steel and the prediction of surface defects that occur in each stage of the forming-sequence have been carried out. To this aim, a series of tensile tests were conducted to evaluate the influence of temperature and strain rate on the materials elasto-plastic properties. Futhermore, an innovative experimental setup was used to reproduce the realistic friction conditions at the tool-workpiece interface, in order to accurately predict metal flow during forging cycles. Experimental data were subsequently validated and implemented in a commercial 3D-FE software and accurately calibrated to perform fully coupled numerical simulations for the reference processes. Finally, the forged parts obtained were characterized by macro- and microstructural inspections in order to evaluate the presence of underfilling problems and surface defects, which were consistent with the numerical FE results coming from both simulated processes (i.e. single- and multi-stage forging), and to analyze the microstructural evolution of α- and γ-phase during single-stage tests both at room temperature and from 400 to 700 °C. The materials investigated in this work are low-carbon AISI 1005 ferritic-pearlitic steel (Wr. N. 1.0303), AISI 304L austenitic (Wr. N. 1.4307) and commercially named Duplex 2205 ferritic-austenitic stainless steel (Wr. N. 1.4462). The developed experimental tests are suitable to proper evaluation of steels behaviour in terms of mechanical properties, and to precisely calibrate coupled numerical models when they are applied to conventional and re-design forging processes. The techniques used in this work include: tensile tests, T-shape compression tests, visual inspections (i.e. supported by vernier calliper and micrometer measurements), hardness and micro-hardness tests, LOM (Light Optical Microscopy), FEG-ESEM (Field-Emission Gun Environmental Scanning Electron Microscope), EDS (Energy Dispersive X-ray Spectroscopy), EBSD (Electron Back Scattering Diffraction) and numerical models carried out with FORGE2011®-3D.
La possibilità di produrre componenti in acciaio inossidabile a costo limitato e caratterizzati da elevate proprietà meccaniche, ha assunto notevole importanza negli ultimi anni. Al giorno d'oggi, i processi di stampaggio a freddo e a semicaldo di acciai al carbonio sono ampiamente usati per produrre componenti industriali, grazie ai loro vantaggi economici, ma è ancora assente in letteratura un'ampia ricerca di nuovi metodi di progettazione industriale di processi di deformazione plastica a freddo e a semicaldo di prodotti in acciaio inossidabile, con la successiva valutazione delle proprietà microstrutturali. Negli ultimi decenni, l'industria dei processi di stampaggio è cambiata rapidamente. Ora i processi produttivi near-net-shape o net-shape stanno diventando una pratica utile nella formatura dei metalli, garantendo notevoli risparmi di materiale ed energetici. Molti componenti, ottenuti con lavorazioni per asportazione di truciolo, possono essere prodotti a basso costo mediante stampaggio a freddo o a semicaldo. Tradizionalmente, la progettazione dei processi di forgiatura avviene utilizzando linee guida empiriche, basate sull'esperienza e su tentativi trail-and-error da parte dei progettisti, che si traducono poi in tempi di sviluppo del processi e costi di produzione elevati. Per evitare ciò, negli ultimi anni, gli approcci di simulazione numerica si sono dimostrati strumenti potenti per prevedere e analizzare la deformazione del materiale mediante processo di formatura. Attualmente sul mercato sono presenti molti pacchetti commerciali adatti a simulare i processi di forgiatura dei metalli e la maggior parte di essi sono concentrati sulla previsione della forma del prodotto finale dopo operazioni di formatura semplici o complesse, mono- o multi-stadio. Altri aspetti vengono inclusi in questi modelli numerici, quali una migliore comprensione del comportamento del materiale, delle condizioni di attrito e lubrificazione e delle proprietà del prodotto finale, per poter prevedere fenomeni più complicati come la stima della vita dell'utensile, delle condizioni di frattura duttile e la valutazione della microstruttura. Lo scopo della presente tesi di dottorato è lo sviluppo di un approccio innovativo basato sulla progettazione di procedure sperimentali integrate con strumenti di modellazione numerica, per riprogettare accuratamente una serie di processi di forgiatura industriali mono-stadio adatti alla produzione di componenti in acciaio inossidabile a diverse temperature. Inoltre è stata effettuata la riprogettazione di un processo di formatura multi-stadio a freddo di un acciaio a basso tenore di carbonio, con la successiva previsione dei difetti superficiali che si verificano in ogni fase della sequenza di formatura. A tale scopo sono stati condotti una serie di test di trazione, per valutare l'influenza della temperatura e della velocità di deformazione sulle proprietà elasto-plastiche dei materiali considerati. Inoltre è stato realizzato un innovativo apparato sperimentale per riprodurre le condizioni di attrito reali all'interfaccia tra lo spezzone e l'utensile, al fine di prevedere con precisione il flusso del metallo in fase di deformazione plastica. I dati sperimentali sono stati validati e implementati in un software commerciale agli elementi finiti 3D-FE e successivamente calibrati con precisione, per effettuare accurate simulazioni numeriche dei processi di riferimento. I componenti forgiati ottenuti sono stati oggetto di indagini macro e microstrutturali, per valutare l'eventuale presenza di difetti superficiali, e analizzare l'evoluzione microstrutturale della fase α e γ a diverse temperature di forgiatura (i.e. 20, 400, 500, 600, 700 °C). I risultati sperimentali sono stati successivamente validati mediante simulazione numerica. I materiali studiati in questo lavoro sono: acciaio ferritico-perlitico AISI 1005 a basso tenore di carbonio (Wr. N. 1.0303), AISI 304L austenitico (Wr. N. 1.4307) e ferritico-austenitico Duplex 2205 (Wr. N. 1.4462). Le prove sperimentali sviluppate sono adatte ad una corretta valutazione del comportamento degli acciai in termini di proprietà meccaniche, calibrando con precisione i modelli numerici se applicate a processi industriali di forgiatura tradizionali e riprogettati. Le tecniche utilizzate in questo lavoro prevedono: test di trazione, test di compressione T-shape, controlli visivi (mediante calibro cinquantesimale e micrometro), misure di durezza e microdurezza, microscopia ottica (LOM), microscopia elettronica a scansione ad emissione di campo (FEG-ESEM), spettroscopia a dispersione di energia (EDS), diffrazione da retrodiffusione elettronica (EBSD) e modelli numerici sviluppati in FORGE2011®-3D.

Abstract:
Ou study focuses on the effects of phase transformations on crack propagation. We want to understand the changes of fracture toughness during welding. In this work, fracture toughness is expressed by J-integral. There are many experimental methods to obtain the critical toughness JIC but they are impractical for our investigation during phase transformation. That is the reason why we have proposed a method coupling mechanical tests, digital image correlation and finite element simulation. The fracture tests are implemented on pre-cracked single edge notched plate sample which is easy for machining and heat conduct during phase transformation. The tests are conducted at different temperatures until rupture. Digital image correlation gives us the displacement information on every sample. Each test is then simulated by finite element where the fracture toughness is evaluated by the method G-Theta at the crack propagation starting moment found by potential drop method and digital image correlation technical. Two materials have been studied, 15Cr-5Ni martensitic precipitation hardening stainless steel and 16MND5 ferritic low carbon steel. For these two materials, different test temperatures were chosen before, during and after phase transformation for testing and failure characterization of the mechanical behavior. Investigation result shows that metallurgical phase transformation has an influence on fracture toughness and further crack propagation. For 15-5PH, the result of J1C shows that the as received 15-5PH has higher fracture toughness than the one at 200°C. The toughness is also higher than the original material after one cycle heat treatment probably due to some residual austenite. Meanwhile, pure austenite 15-5PH at 200°C has higher fracture toughness than pure martensitic 15-5PH at 200°C. For 16MND5, the result also proves that the phase transformation affects fracture toughness. The as received material has bigger J1C than the situation where it was heated to 600°C. On the other hand, the material at 600°C just before isothermal bainite transformation after the austenitization during cooling process also has higher fracture toughness than the one at 600°C before austenitization. These two conclusions are consistent well with the result of 15-5PH. But the final situation of 16MND5 after one cycle heat treatment has a slightly smaller J1C than the receiving situation. It means that one cycle heat treatment hasn't an significant influence on 16MND5fracture toughness. Conclusions show that one should pay attention to the heating period before austenitization of the substrate material when people do the welding as the higher temperature will bring the lower fracture toughness during this process. While during cooling period, the fracture toughness doesn't change a lot during, before or after the cooling induced phase transformation. Even for 15-5PH, it has a better fracture toughness after the martensite transformation than before.

Abstract:
Forging is a metal forming process commonly used in industry. Forging process is strongly affected by the process temperature. In hot forging process, a wide range of materials can be used and even complex geometries can be formed. However in cold forging, only low carbon steels as ferrous material with simple geometries can be forged and high capacity forging machinery is required. Warm forging compromise the advantages and disadvantages of hot and cold forging processes. In warm forging process, a product having better tolerances can be produced compared to hot forging process and a large range of materials can be forged compared to cold forging process. In this study, forging of a particular part which is being produced by hot forging at 1200°
C for automotive industry and have been made of 1020 carbon steel, is analyzed by the finite volume analysis software for a temperature range of 850-1200°
C. Experimental study has been conducted for the same temperature range in a forging company. A good agreement for the results has been observed.

Published Article
Selective laser micro-welding (SLMW) is a recent rapid manufacturing technique that produces metal parts through the use of a laser beam that selectively scans over the powder layers and fully melts and micro-welds the metallic particles. The advantage of SLMW is that any type of commercial steel alloys or other metal powders can be used to build parts in a single step without the need to add low melting point additives to join the particles as in the former SLS process. In this study, two types of low cost general purpose powders were evaluated as the raw materials for the selective laser micro-welding (SLMW): one powder is AISI304 stainless steel powder from Hoganas, Belgium (cost = $11/kg) and the other isAISI100510w carbon steel locally produced in-house from scrap steel using gas atomizing then de-oxidizing techniques (cost = $1.2/kg). Twelve sample parts were fabricated using two different laser speeds, 70 and 100 mm/s. Dimensions, density, hardness, tensile and microstructure properties were evaluated. Results showed that both powders successfully produced complete parts with accurate dimensions and fine details. Both microstructure phases were austenite due to the rapid heating and cooling cycles. At the higher speed of 100 mm/s mechanical properties deteriorated because of the porosities inside the structure. Using low cost powders gives more potential for the SLMW to spread as an economical manufacturing process in the near future.

La caractérisation des couches d'oxydes formées après traitement est réalisée par différentes méthodes : spectroscopie optique de réflexion (UV-VIS proche IR, IRFT) ; diffraction des rayons X ; spectroscopie Mössbauer et MEB-EDS. L'analyse de ces couches montre l'apparition de Fe2O3 et de Fe3O4 dans le cas des aciers faiblement alliés, de Fe2O3 et d'oxydes mixtes de fer et de chrome (Cr2-xFexO3, Fe1+xCr2-xO4) dans le cas des inox. L'apport thermique et l'augmentation de la puissance électrique favorisent l'évolution de l'épaisseur de la couche d'oxydes. L'analyse par spectroscopie d'émission d'un plasma d'air obtenue par décharge glissante révèle la présence de l'oxygène atomique et d'espèces moléculaires (radicaux OH et monoxyde d'azote NO) dans la décharge.

The purpose of this research is to study the effect of adding several fluxes on the weld penetration and mechanical properties of SAE 1020 low-carbon steel and AISI 304 stainless steel. Butt joint argon MIG(Metal Inert Gas) welding process was made on low-carbon steel SAE 1020 and stainless steel AISI 304 plate. The activating fluxes used in the experiment were MnO2, MgCO3, Cr2O3, MoS2, NiO, MoO3, MgO, Fe2O3, ZnO, SiO2 and TiO2. The experiment found that when using torch moving speed of 346 mm/min and welding voltage of 23.3 V, it will be better mechanical properties. The flux MnO2 is the best of all fluxes according to the weld depth/width ratio(D/W ratio) and reduce the weld FN(ferrite content). The mixed fluxes MoS2-MoO3 can enhance the welding penetration and fusion zone, and it can improve the mechanical properties of the weld micro-hardness and FN. Finally, by employing the Taguchi Methods to achieve optimized welding penetration and the D/W ratio, which were welding voltages, argon flow rate, welding torch travel speed and the weight ratio of MoS2 and MoO3. From the results of Taguchi Methods experiment, the optimal welding parameters for joining of the SAE 1020 carbon steel and the AISI 304 austenitic stainless steel are (1) welding voltages of 21.4 V; (2) argon flow rate of 8 l/min; (3) welding torch travel speed of 403 mm/min; and (4) mixed powder combination of 20% MoS2 and 80% MoO3. Beside, from the results of analysis of variance (ANOVA), the orders of the importance on the D/W ratio of weld pool geometry within the four control factors are (1) welding voltages; (2) mixed powder; (3) welding torch travel speed; and (4) argon flow rate.

Butt joints of the A5052 aluminum alloy and the SS400 steel, along with a new type of chamfered edge are formed by means of metal inert gas welding (MIG) and the use of the ER4043 Al-Si filler metal. The micro-hardness and micro-structure of the joint are investigated. An inter-metallic layer is found on the surface of the welding seam and the SS400 steel sheet. The hardness of the inter-metallic layer is examined using the Vickers hardness test. The average hardness values within and without the Intermetallic (IMC) layer zone were found to be higher than those of the ER4043 welding wire. The tensile strength test showed a fracture at the inter-metallic layer when the tensile strength is rated at 225.9 MPa. The tensile value test indicated the average of welds was equivalent to an 85% tensile strength of the A5052 aluminum alloy. The thickness of the inter-metallic layers is non-uniform at different positions, with ranges from 1.95 to 5 μm. The quality of the butt joints is better if the inter-metallic layer is minimized. The Si crystals which appeared at the welding seam indicate that this element participated actively during the welding process, and it also contributed to the IMC layer’s overall formation. The T-joint of the A6061 alloys and the SUS304 stainless steel utilized new welding rods of Aluma-Steel by means of the Tungsten Inert Gas (TIG) welding process. The mechanical properties, such as the characteristic of micro-structure, along with a component analysis of the welds, has been investigated by means of mechanical testing, micro-hardness testing, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). As a result, fracturing may have occurred at the adjacent area between the welding seam and the A6061 aluminum alloy plate. The average micro-hardness between the welding seam and the SUS304 stainless steel is rated at 279.72 HV, and the welding seam and the A6061 aluminum alloy is 274.50 HV. A large amount of copper elements were found to be present in the welds due to the use of the new Aluma-Steel welding rod.

The relationship among mechanical properties, phase ratios, and microstructures is investigated by using 3 kinds of low carbon and extra-low carbon steel wire materials which are usually applied to make screws and bolts in this study. And Electron Microscopes(EM), Energy Dispersive Spectrometers(EDS), and X-ray Diffraction Meters are provided to distinguish the types of precipitates. Moreover, the differences of the forged streamlines are observed and compared after the wire materials are formed to screws. The results show that the precipitate phase of tatanium nitrides and tatanium carbides exists in the extra-low carbon steels so that the hardness values of the extra-low carbon steel wire materials formed after cold forging raise for 10 % compared with low carbon steel wire materials. Besides, the wire materials which contain extra-low carbon steels and are mixed with Titanium elements appear course feritite grains. They can be made as cold forging machining wire materials; that is, the softened annealing treatment is not necessary, but the ductility keeps excellent. This results in a smooth forging streamline. Therefore, on the property study under different carbon content wire materials, it is the best wire materials to save a lot of money not to pay the processing cost because of no annealing treatment requirement and to be still formed through cold forging only.

Abstract Martensitic stainless steels are essentially iron-chromium-carbon alloys that possess a body-centered tetragonal crystal structure (martensitic) in the hardened condition. Martensitic stainless steels are similar to plain carbon or low-alloy steels that are austenitized, hardened by quenching, and then tempered for increased ductility and toughness. This chapter provides a basic understanding of grade designations, properties, corrosion resistance, and general welding considerations of martensitic stainless steels. It also discusses the causes for hydrogen-induced cracking in martensitic stainless steels and describes sulfide stress corrosion resistance of type 410 weldments.

Abstract:
Abstract Forged stainless steels are commonly used for the containment of hydrogen isotopes and fracture toughness properties are needed for structural integrity assessments. In this study, the effects of hydrogen and tritium precharging on the fracture-toughness properties of Types 316L and 304L stainless steel forgings were measured. The purpose of the study was to evaluate hydrogen and tritium effects on fracture toughness properties of: (1) Type 316 stainless steel stem-shaped and cup shaped forgings; and (2) Type 304L cylindrical block forgings with two different yield strengths. Arc-shaped fracture toughness specimens were cut from the forgings and precharged by exposing the specimens to hydrogen or tritium gas at 623K and 34.5 MPa. Tritium precharged specimens were aged at 193 K for 45 months prior to testing to build-in helium-3 from tritium decay. In the as-received condition, the J-Integral fracture toughness of the stem, cup, and block forgings were very high and exceeded 1200 kJ/m2 on average. The fracture toughness of specimens cut from the low yield strength Type 304L stainless steel block forging had the highest fracture toughness values and Type 316L stainless steel cup forging had the lowest. The reduced fracture toughness values were attributed to the large strain required to produce the cup forging and its high yield strength. Hydrogen precharging reduced the fracture toughness of the stem, cup, and block forgings to values between 34%–51% of a baseline value which was taken to be the fracture toughness value of the low yield strength block forging. Tritium precharging reduced the fracture-toughness values more than hydrogen precharging because of the effects of helium from radioactive decay of tritium. The fracture-toughness properties of tritium-precharged forgings ranged from 12% to 23% of the baseline values. In general, Type 316L stainless steel was more resistant to toughness reductions by hydrogen or tritium (and decay helium) than Type 304L stainless steel. Yield strength had only minor effects on fracture toughness for the precharged steels.

Abstract:
In order to gain high strength, fine grain size, stronger anti-corrosion property, and especially low permeability, the material 022Cr19Ni10N was chosen to manufacture the Rod Travel Housing Forging (RTHF) for Control Rod Drive Mechanism (CRDM). But, cracks were found in some forgings failing to meet the requirements of ultrasonic testing (UT). The causes of the forging cracks of this austenitic stainless steel forging were investigated by means of metallography, scanning electron microscopy (SEM) and other experimental methodology. The results indicated that the second δ-ferrite phase leads to the forging cracks between γ-δ interface during the low temperature forging process, and finally leads to the forging failure. It’s found that the cracks are distributing along the stripe δ-ferrite, and almost distributing in the same area as the large size δ-ferrite by metallography & SEM microstructure observation. The δ-ferrite is firstly found in the electroslag ingot, and in which, the distribution and size is different from the case to the core. The largest size δ-ferrite is around the core area, and this characteristic passes on to the final forging microstructure, although the shape, quantity & distribution of the δ-ferrite changed during the manufacturing process. Most forging cracks were found around the core area of the forging by UT examination. In the final forging process, when the forging temperature drops to 750∼850°C, the δ-ferrite have been forged to stripe shape and hundreds-micron size while the plasticity of the austenite reduce. What’s more, there are large hot plasticity differences between the δ-ferrite and the austenite, so the forging cracks initiate between γ-δ interface and extend to the area around to be a long crack in the low temperature forging process. In order to avoid the forging cracks in the Rod Travel Housing Forging, it’s necessary to reduce the content of δ-ferrite or improve the final forging temperature. Improving the final forging temperature, to guarantee the plasticity of the δ-ferrite and austenite, is another process to reduce the cracks. But while the temperature improves, the grain size grows rapidly, and may form mixed structure. So the most effective mean to reduce the content of δ-ferrite is to redesign the chemical components, mainly by increasing the nitrogen content from 0.06 (wt, %) to 0.12(wt, %), which makes the low temperature forging process for fine grain size possible. In the high-nitrogen-content forging, the δ-ferrite distributed sporadically and no δ-ferrite strip is found. By increasing the austenite forming elements (especially nitrogen), the cracks during low temperature forging process are avoided. What’s more, owning to the optimization of chemical compositions and manufacturing processes, the Rod Travel Housing Forging got fine grain size, low relative permeability, and good comprehensive mechanical properties with the ultimate tensile strength up to 570MPa.

Abstract:
Extrusion process produces semi-finished product that provides significant savings in machining and fabrication of the finished components. Plymouth Engineered Shapes (PES) employs forward extrusion techniques to produce products up to 40 feet long that are utilized in power generation, nuclear, and petrochemical applications where it is critical to meet or exceed ASME piping, boiler and pressure vessels code specifications. The extrusion process has been successfully employed to manufacture components such as various types of valve bodies, manifolds, adapters and more that are targeted for elevated temperature applications up to 1200°F and under high pressures up to 10,000 PSIG. Critical product characteristics include flatness, straightness, twist, angularity, surface quality and dimensions over the full length. This paper presents an overview of the carbon steel and stainless steel extrusion process, the room temperature and elevated temperature mechanical properties, metallographic characterization, testing requirements and the applications of such products. Properties are also be compared to those produced by the conventional hot rolling and forging operations.

This paper presents predictions of weld residual stresses in a mockup with a partial arc excavate and weld repair (EWR) utilizing finite element analysis (FEA). The partial arc EWR is a mitigation option to address stress corrosion cracking (SCC) in nuclear power plant piping systems. The mockup is a dissimilar metal weld (DMW) consisting of an SA-508 Class 3 low alloy steel forging buttered with Alloy 182 welded to a Type 316L stainless steel plate with Alloy 82/182 weld metal. This material configuration represents a typical DMW of original construction in a pressurized water reactor (PWR). After simulating the original construction piping joint, the outer half of the DMW is excavated and repaired with Alloy 52M weld metal to simulate a partial arc EWR. The FEA performed simulates the EWR weld bead sequence and applies three-dimensional (3D) modeling to evaluate the weld residual stresses. Bi-directional weld residual stresses are also assessed for impacts on the original construction DMW. The FEA predicted residual stresses follow expected trends and compare favorably to the results of experimental measurements performed on the mockup. The 3D FEA process presented herein represents a validated method to evaluate weld residual stresses as required by ASME Code Case N-847 for implementing a partial arc EWR, which is currently being considered via letter ballot at ASME BPV Standards Committee XI.

Abstract:
This paper presents a finite element analysis (FEA) based approach to perform crack growth evaluation of remnant cracks in a mockup with a partial arc excavate and weld repair (EWR). The partial arc EWR is a mitigation option to address stress corrosion cracking (SCC) in nuclear power plant piping systems. The mockup is a dissimilar metal weld (DMW) consisting of an SA-508 Class 3 low alloy steel forging buttered with Alloy 182 welded to a Type 316L stainless steel plate with Alloy 82/182 weld metal. This material configuration represents a typical DMW of original construction in a pressurized water reactor (PWR). To create a representative partial arc EWR application, the outer half of the DMW is excavated and repaired with Alloy 52M weld metal. The crack growth evaluation process presented herein represents an advanced method to evaluate the Alloy 82/182 remnant crack growth as required by ASME Code Case N-847 for implementing a partial arc EWR, which is currently being considered via letter ballot at ASME BPV Standards Committee XI. After the repair, any crack that remains in the Alloy 82/182 remnant and underneath the EWR needs to be evaluated for stress corrosion cracking (SCC) to assess its potential to grow beyond the EWR coverage area. Conventional fracture mechanics approach may not be suitable to evaluate such a remnant crack because of its close proximity to multiple materials of different mechanical properties and unconventional crack shape. In the crack growth evaluation, a crack that is reminiscent of a circumferential crack in a pipe, and a crack that is reminiscent of a laminar crack in a pipe are evaluated to predict the time for each of them to grow beyond the partial arc EWR coverage arc length. It is expected that the approach, analysis steps, calculation procedures presented in this paper will be applicable to analyzing a pipe geometry using realistic residual stresses and operating stresses for an EWR.

Abstract:
Abstract Stainless steels along with Nickel based alloys are often selected for many applications in corrosive environments. While resistance to corrosion makes them a favorable choice, poor tribological behavior may prevent a broader use of these materials. The Kolsterising® process is a proven method for the surface hardening of these materials by the diffusion of carbon. This paper intends to highlight the improvements typically seen in key mechanical properties including resistance to galling, wear resistance, and fatigue life. Untypically, due to the nature of the process, these properties are generally improved without the usual associated reduction in corrosion resistance. Property improvements will be demonstrated using both new and existing data from Europe and North America.
