Abstract:
Abstract Recently, the castings made from aluminum-silicon alloys by pressure die casting are increasingly used in the automotive industry. In practice, on these castings are high demands, mainly demands on quality of their structure, operating life and safety ensuring of their utilization. The AlSi5Cu3 alloy castings are widely used for production of car components. After the prescribed tests, the cracks and low mechanical properties have been identified for several castings of this alloy, which were produced by low pressure casting into a metal mould and subsequent they were heat treated. Therefore, analyses of the castings were realized to determine the causes of these defects. Evaluation of structure of the AlSi5Cu3 alloy and causes of failure were the subjects of investigation presented in this article.

Abstract:
The analysis of the world market of metal castings in 2019–2021 is presented. Due to the fact that as of January 2022 the publication of the world statistics of the production of metal castings did not take place, an analysis of information was carried out regarding the results in the countries that are part of the global Top-10. Among them are China, India, USA, Germany, Japan, Turkey and Brazil. It is noted that in 2021 in China, 54.05 million tons of castings were produced, which is 4.0% more than in 2020. In terms of cast alloys: gray cast iron (share 41.7%), cast iron with nodular graphite (29.5%), aluminum and magnesium alloys (13.3%) and steel (12.2%). In India, the export of metal castings in terms of value for the period from 2016/2017 financial year (FY) to 2020/2021 F. increased from 2.366 to 2.865 billion USD, i.e. with a CAGR of 3.9%. In the USA for the period from 2013 to 2019 the income of the foundry industry increased from 38.7 to 44.3 billion USD, that is, with an average annual growth rate (CAGR) of 1.9%. Under the influence of the COVID-19 pandemic and the slowdown of the economy in 2020. industry revenue decreased to USD 36.7 billion (-17.1% vs. 2019). However, in 2021 the situation improved somewhat ― 43.4 billion USD (18.3% against 2020). In Germany, the production of castings from ferrous metal alloys (gray cast iron, with nodular graphite, malleable and steel) in 2021. amounted to 3.2 million tons, which is 16.4% more than in 2020. At the same time, for the period 2019-2021 production of the specified castings decreased at an average annual rate (CAGR) of -6.0%, and their export ― by -7.0%. In Japan, as a result of the changing economic situation in the world, which was formed after 2019, the production of castings during 2019-2021. is characterized by a downward trend. The production of castings from copper alloys decreased with an average annual rate (CAGR) of -5.6%, castings from aluminum alloys ― -5.1% and castings from iron alloys ― -1.5%. In Turkey in 2021 1.108 million tons of nodular cast iron castings (by 29.6% vs. 2020), 0.921 million tons of gray iron castings (by 49.1%) and 0.279 million tons of steel castings (by 45, 4%). In general, during 2019–2021 the production of castings from ferrous metal alloys in the country increased at an average annual rate (CAGR) of 9.9%. In Brazil, in 2021, foundry enterprises produced 2.5 million tons of castings, which is 21.1% higher than in 2020. At the same time, the production of castings from cast iron increased by 25.5%, from non-ferrous metal alloys ― by 7.0%, and steel ― by 3.9%. In general, during 2019–2021 the production of castings in the country increased at an average annual rate (CAGR) of 3.1%. The presented data indicate that in 2021 the global foundry industry developed in a positive trend. Estimated global production of castings from ferrous and non-ferrous metals by the end of 2021. may amount to 109.2...118.5 million tons against 105.5 million tons in 2020. However, as a result of the war between Russia and Ukraine, a number of negative factors have arisen that will cause a slowdown in foundry production in 2022–2023. The review also presents information about the world’s leading foundry companies, as well as examples of the use of 3-D printing in foundry production in the United States and Great Britain.

Abstract:
In addition to aluminium and titanium alloys, the magnesium alloys comprise the group of lightweight alloys which have the highest practical importance in structural applications. The WE43 alloy with the addition of rare earth elements and yttrium is used mainly for the sand mould castings for the aerospace industry. The castings for aerospace industry have complicated shapes and varying wall thickness, as a result of which they often have casting effects such as misruns, micro-shrinkages and cracks. The frequency of defect occurrence in the complicated shape casting may exceed 50%. The defects are repaired by means of welding and pad welding. Such practice is often used in foundries. The paper presents the results of repair evaluation of the WE43 alloy castings in the as-cast state by means of the TIG welding. The welding tests have been performed on the joints bevelled to “I”, “Y” and “V” and the technological repair guidelines have been formulated. The defect has been repaired and the non-destructive and structural tests have confirmed that the technology is correct. The WE43 alloy should be welded and pad welded with maximum linear arc energy of 3.0 kJ/cm, straight beads, with filler metal of a similar chemical composition, in the as-delivered state.

Abstract:
The article studies new heat-resistant and wear resistant materials for operation under extreme conditions, especially in the power industry. The methods that improve the quality of a metal in metal castings through the influence of alloying elements on its structure and properties have been considered. These methods are very effective for reducing the tendency of a metal to form a coarse–grained structure. The paper describes optimal techniques for melting special alloys in induction and electric furnaces. A set of rules for the selection of a melting temperature before pouring a metal into the casting forms depending on the dimensions, wall thickness, geometry of castings have been determined. The behavior of new alloys under the conditions of high temperatures, aggressive environments has been studied. It has been established that heat–resistant Cr–Al steels exhibit high heat resistance and wear resistance properties; they 6–8 times surpass Cr–Ni steels in oxidation resistance. The proposed Cr–Mn cast iron processed in an integrated manner with REM (rare earth metals) and Ti is superior to a basic cast iron in conditions of a heavy wear. Numerous industrial trials confirm the usefulness of recommended new casting materials for use under extreme conditions.

Abstract:
An analysis of the state of foundry production in Ukraine is presented. The foundry industry of Ukraine in the 21st century significantly reduced its production indicators, which is due to the influence of such factors as the stagnation of industries that consume metal castings, as well as a decrease in exports. This situation has been negatively affected by the COVID-19 pandemic, as well as the global foundry industry, due to a decrease in demand for castings from end manufacturers. It was predicted that positive developments should be expected in the near future. However, russia's attack on Ukraine on February 24, 2022 made a significant correction in the development of the global economy, and, accordingly, in the functioning of the world foundry industry. Ukrainian companies in the foundry industry felt the impact of the war, some of them suffered partial destruction of their production premises. Large foundry enterprises of Ukraine are mostly located in the south-eastern regions, which were the most affected by hostilities. At the same time, in order to reflect the real situation in the foundry industry of Ukraine, it is advisable to organize the collection of real data regarding the production of castings from various alloys in the country, as well as regarding the export and import of foundry products. This will make it possible to make effective decisions regarding the program of modernization of the industry and the development of industries that consume domestic metal castings. Ultimately, this will help increase the competitiveness of Ukrainian products and increase revenues to the budget of Ukraine. To assess the direction of development of foundry production in advanced countries of the world, the statistical data of the leading countries regarding the production of castings and in more detail such countries as Poland, Germany and the USA are given. The structure of cast products produced in the world is in constant dynamics and there is a constant change in the ratio of the volumes of castings produced from various alloys. Recent years have been characterized by a tendency to reduce the production of castings from steel and gray iron with a simultaneous increase in the share of castings from highstrength cast iron and aluminum alloys.

Abstract:
In casting industry the selection of mold material and molding method is challenging task. There are several types of molding methods, but over 70% of all metal castings are generally developed by means of sand molding (sand casting). Sand casting has two processes such as, green sand casting and chemically bonded sand casting process. This paper focuses on chemically bonded sand casting i.e. no-bake sand system (self-hardening system), among from all types of no-bake sand system, alkaline phenolic ester cured (ALPHASET) and furan acid cured no-bake system are preferably discussed. Curing mechanism of all type of no-bake systems are shown along with detailing about ALPHASET and furan no-bake sand system.

Abstract:
Experimentally investigate the intensity and specificity of the processing of different types of metal castings of the zipper in a tensile machine with complex spatial movement of the working capacity, to obtain the appropriate calculation dependencies to determine the processing time. An experimental study of the separation from the casters of three types of metal castings of the zipper (casting with two, with eight fixed details-cases and outflow with sixteen fixed details by clamps) in a tensile machine with a complex spatial movement of the working capacity by observing the change in the number of machined parts during the process. Further mathematical processing of the obtained results is carried out. The types of castings for which the maximum and minimum technological time are spent in the toughening machine with complex spatial movement of the working capacity are determined. It is established that for processing castings with fixed parts-locks it takes twice more technological time, which is spent to clean the separated parts from the remnants of the wrap and burrs. Compared with conventional rotating shredding machines, using machines with complex spatial movement of the working capacity, you can increase the productivity of this technological operation by almost ten times. The dependences between different types of metallic castings of the zipper and the intensity of separation of parts from them during processing in a caulking machine with a complex spatial movement of the working capacity with providing a waterfall mode of movement and 50% filling the capacity. Appropriate design dependencies were obtained to determine the processing time. Guidelines on the implementation of rational technological parameters in the processing of various types of metal castings of the zipper in a tensile machine with a complex spatial movement of the working capacity. These guidelines can be used at the design stage of technological processes and equipment in the relevant machine-building and light industry enterprises specializing in the manufacture of hardware.

Abstract:
AbstractAlthough continuous casting became the state of the art for the casting of ordinary steel grades, ingot casting by bottom teeming still has relevance in the steelmaking industry, especially for the manufacturing of specialty and alloy steels. As for every casting process, the ever-increasing quality requirements by customers lead to increased demand for new technologies to increase the purity of the cast steel melt regarding its inclusion content. Due to the special design of the bottom-teeming ingot casting facility and the discontinuous operation as batch process, the application of filters is a promising approach. Tailored foam geometries were prepared based on additive manufacturing via selective laser sintering (SLS) and transformed into filters via modified replication techniques and flame spraying. Additionally to filter application, the functionalization and quality improvement of applied hollowware refractories has high potential to remove existing inclusions from the steel melt and avoid the formation of new inclusions during casting. The investigated hollowware components were manufactured by pressure slip casting on the basis of coarse-grained alumina compositions and subsequent functionalization by spray coating based on carbon-bonded alumina slurries. Simultaneous application of functionalized, “reactive” refractory components and flame-sprayed, “active” filters enables a combined filtration system which unites the advantages of the distinct filtration mechanisms. In the continuous casting of specialty steels, the conditions are more severe resulting in additional challenges regarding the application of filters. An approach investigated in this subproject is the use of extruded filter starter casting tubes above the tundish outlet. To achieve this, extrusion mixes based on cellulose derivatives and materials of the system Al2O3-ZrO2-C (AZC) were investigated for their suitability. The new concepts were tested in industrial casting trials in cooperation with the company Deutsche Edelstahlwerke Specialty Steels Europe GmbH (DEW). Post-mortem, the former melt-refractory interface of the applied components was investigated and steel samples from the ladle, the gating system and the ingot were analyzed in comparison to untreated samples.

Abstract:
AbstractEven though ceramic foam filters for metal melt filtration have been used in the casting industry for many decades, the filtration mechanisms have not yet been satisfactorily determined. Due to the opaqueness of the melt and the need for high operating temperatures as well as the complexity of the aluminum casting process, filtration experiments are expensive and a detailed insight into the filtration process is hardly achievable. However, the analysis by means of a model system contributes to an essential understanding of the processes taking place. Metal melt systems are characterized by their high surface tension resulting in poor wettability of the solid surfaces in contact with the liquid melt. Therefore, the model system needs to exhibit both similar flow characteristics and wetting properties as the melt system to obtain reliable results. In this study, water was used as the model liquid and the wetting properties of the solid surfaces have been modified to mimic the characteristic wetting behavior of the melt-filter interface. The influence of filter and particle properties as well as process parameters on the filtration efficiency of ceramic foam filters have been investigated. In order to minimize possible overlapping effects in the determination of individual parameters influencing the separation efficiency, care was taken to vary only one parameter, so that the filtration is only dependent on one variable. Besides water-based filtration experiments, it is also possible to have a closer look on interaction forces between inclusion particles and the filter wall and how a higher filtration efficiency can be achieved. Here, too, a water-based model system is beneficial due to the same issues of available devices and costs.

Abstract:
AbstractConcrete is one of the fundamental materials in the construction industry. Typically, concrete is composed of sand, cement, aggregate, and added water to the cement ratio. To enhance sustainability and reduce the negative effect on the environment from industrial waste, recycling waste material into the concrete mixture is becoming an area of research by substituting some of the concrete ingredients with some of the recycled waste material in order to reduce the amount of fine natural aggregate used in the construction industry, maximise the strength and minimise the overall weight of the concrete product. Waste foundry sand is a by-product of sand casting, a waste product of the metal casting industry. The improper disposal of this waste foundry sand (WFS) could cause environmental issues. Consequently, its possible use in building materials, product design, construction, and other fields is crucial for mitigating environmental limitations. To minimise negative environmental impacts, researchers have proposed reusing this waste foundry sand by replacing, fully or partially, some of the standard natural sand within the concrete mixture. This paper investigates the mechanical and physical properties of concrete cubes containing recycled sand-casting material by demonstrating the experimental work to determine the potential benefit or limitations of using this material within the concrete in the construction and product design industries. According to the experimental results, waste foundry sand, with a substitution ratio of up to 30%, had a compression strength of circa 23 N/mm2 and reached up to 78% of the strength of a standard control sample within 7 days. The results hence suggest that waste foundry sand can be used in the production of concrete products when such reduction in strength is not critical. Such a range of products could include curbs, garden slabs, cycling pavements, gravel boards, etc. Additionally, utilising waste foundry sand will help to reduce the use of natural sand and the need for landfill sites, which has several advantages, including cost savings and environmental protection by reducing CO2 emissions during transportation.

Abstract:
In the production of cast engineering products, in several cases, it becomes expedient to create differentiated (gradient) structures in castings to increase the special properties and service life of cast products. The purpose of this work was to establish the regularities of the formation of the main macrostructural zones in the cross-section of castings of carbon pre-eutectoid steels and quantitative changes in their length depending on the thermokinetic conditions of crystallization. The research was carried out on rectangular castings made of 20L, 45L and U7L steels, size 115 × 130 × 200 mm, with provision during their crystallization of one-sided predominant cooling of the end part of the castings with different intensity of heat removal - 5 °С/s, 60 °С/s and 300 °С /with. Research was carried out on templates from the central longitudinal part of castings that crystallized under conditions of directed one-sided heat removal. The obtained experimental results indicate regular changes in the morphology and length of the macrostructural zones of castings depending on the determining parameters of crystallization - the intensity of cooling and the temperature interval of the solid-liquid state of the melt. The maximum values of the length of the transcrystallization zone and the zone of branched dendrites are observed in steel with a low carbon content (0.21%) and the lowest crystallization temperature interval (40 °С) during hardening under the conditions of rapid cooling of the melt (300 °С/s). During crystallization with a low cooling rate of the melt (5 °C/s), the zones of branched crystals in castings of 20L steel and large equiaxed crystals in U7L steel with a narrow (40 °C) and wide (115 °C) crystallization interval acquire the greatest development. Regression analysis of the results of the experiments established the regularities of the influence of the studied thermokinetic parameters on the gradient of the structure along the cross-section of steel castings. The obtained results of research on the influence of thermokinetic parameters on the processes of crystallization and formation of gradient structures in steel castings open up new opportunities for forecasting and purposeful influence on the structure formation and mechanical properties of cast steel parts. Keywords: steel, crystallization, gradient structure, thermokinetic parameters.

Abstract:
A consistent casting process can sometimes be a challenge to achieve due to the wide array of initial conditions that can affect the process. Variation in these initial conditions during the casting process can generate an array of unexpected results, which sometimes have a negative effect on the structural integrity of the castings. Cold shuts, shrinkage formation, and hot tears are just a few examples of the defects that can arise. Throughout the history of the railroad, castings found with these types of defects have plagued the industry. Since castings are considered a leading method for manufacturing metal components, it is important to have a consistent and repeatable process. Without this, defects can drive the quality of the product down and cause castings to fail while in service. Studying the effects of initial condition variance can teach us which parameters can positively or negatively affect the overall casting process. Improvements in a foundry’s process can then be implemented resulting in a more consistent, reliable final product. Computer simulation software has proven to assist in predicting defects before a single casting has even been poured. As with any simulation, care must be taken when setting up the input parameters. Without careful consideration of the initial conditions, the results may not reflect the actual process. Because of this fact, Strato, Inc. continues researching and sharing its findings regarding the effectiveness of these simulations. This research helps to ensure that a higher quality product with a lower fall-out rate is delivered promptly to the customer. Specific initial conditions are explored in this paper. Variance in the soundness of the casting process is examined through the use of material density plots. These density plots, which provide a visual indication of internal shrinkage, have been obtained using simulation software. These predictions of shrinkage are then compared to actual castings that were poured using the same initial conditions. Results from the following three case studies present evidence to further the belief that using this software, which allows for a deeper understanding of the thermal and fluid dynamics of the casting process, has a direct impact on both quality, as well as the time it takes to develop a sound process. With the knowledge gained by simulating variance in initial casting conditions, a more robust rigging design and overall casting process can be achieved. This paper is a continuation of Strato’s investigation into the effects of varying initial conditions with simulation software and comparison with real world results. The first part was presented at the 2012 ASME JRC and can be found within its proceedings. Although some concepts and terms are explained in both papers, it is suggested that part one of this paper be reviewed by those who would like more insight into the framework of this paper.

Abstract:
The investment casting (IC) process has remained relatively unchanged throughout recorded history [1]. Indeed, there have been refinements to the individual processes required to produce castings; pattern making, the ceramic materials used to create the molds, foundry equipment, and post-cast processing of the castings. All have undergone numerous improvements. Yet, with the innovations that IC foundries have enjoyed, the casting process still requires a one-to-one ratio to produce an IC component from a sacrificial master pattern [2]. It is the alternative technologies used to produce the sacrificial master pattern that are the focus of this paper. New product development and introduction (NPDI) of an IC component requires the expertise of several engineering disciplines. Communications between the various engineering disciplines are critical to assure that cost effective decisions during product design and process development are made. With that in mind, several of the options available to the engineering teams responsible for NPDI are explored in the subsequent text. Rapid prototype (RP) technologies have played a crucial role during NPDI. The patterns produced using the various forms of RP technologies have allowed the IC industry to be considered by design engineers as a viable manufacturing option for their products. A more recent development in the United States is rapid tooling (RT). RT is an additive process, using metal to build the individual layers of the cavity block or the cavity insert. The finished component can then be used as a wax pattern cavity. Engineering teams should also consider a combination of RT and traditional wax pattern tooling. The complex pattern cavities are produced using RT while the more simple components are produced using traditional tooling. For IC foundries to be competitive all available pattern making options must be considered. Multi-disciplined engineering teams will play an important role choosing the technologies discussed. With careful consideration, the engineering teams responsible for NPDI can ensure the future of the IC industry.

Abstract:
IN 939 alloy, developed by the International Nickel Co. in the late 1960s, is a unique 22% Cr hot corrosion resistant γ′ strengthened, cast nickel-base superalloy. It is widely used in industrial gas turbines for equiaxed vanes, vane segments and burner nozzles and is of interest to the aero turbine industry for LP and PT integral nozzles (vane rings) and high temperature turbine casings. However, IN 939 is considered difficult to weld repair without parent metal microcracking and can exhibit marginal ductility in heavy section castings. Cannon-Muskegon has developed a proprietary chemistry modified version of IN 939 alloy designated CM 939 Weldable®. Emphasis has been directed on optimizing aim chemistry and ultra high purity manufacture using CM-developed single crystal superalloy melting and raw material technology and subsequently on obtaining superior casting microstructure for improved weldability and mechanical properties. Alloy purity and heat cleanliness will be discussed, along with a simplified two-step heat treatment cycle, resulting in attractive microstructure, mechanical properties and repair weldability. Significant market interest has resulted in extensive vacuum casting experience throughout the gas turbine industry. Excellent results in terms of fluidity, casting cleanliness and minimal microporosity have been obtained without any hot tearing or hot cracking problems.

Abstract:
Abstract The three most popular choices currently used for the main structural components of machine tools are steel weldments, metal (cast iron) castings and polymer composites. Among the three, polymer composite offers the highest vibration damping and the lowest thermal conductivity. All three approaches have been employed in the design of machine tools to meet the criteria for required rigidity, impact resistance and vibration damping. The final choice is also affected by additional factors including cost footprint (space) requirements and lead times. For most production applications of machine tool structures, (gray cast iron) metal castings remain the primary choice because of cost, ease of sourcing, good damping with relatively high strength, good machinability and well-established and consistently achievable manufacturing and processing requirements. However, fabrications are normally the preferred choice for low volume production of large structures, due mainly to the high up-front molding costs and the difficulties in process control inherent in very large castings. On the other hand, with increasing, emphasis on high speed machining, hard turning, and better and consistent machining accuracies, structural rigidity, thermal stability and vibration damping are becoming major design considerations making polymer composites a leading choice. For this reason, Hardinge Inc., a super precision machine tool builder has traditionally used its proprietary polymer composite (Harcrete®) in its lathe, grinder and machining center bases. Depending on the performance and cost requirements, the base can be all composite or a combination of conventional casting strategically reinforced with composite. With the current market forces and ever increasing competition in the industry, for most machines, value engineering has become a prominent factor. A major consideration is to identify the materials and designs that would provide the best performance of the machine while minimizing the cost. Therefore, new sets of evaluation criteria are necessary to arrive at designs with optimum cumulative impact on various technical, commercial and strategic requirements. This paper proposes such new criteria and examines their suitability based on testing and analyses of structural components in today’s demanding real-world machine tool applications.

Abstract:
The fabrication of near net shape powder metal (PM) components by hot isostatic pressing (HIP) has been an important manufacturing technology for steel and stainless steel alloys since about 1985. The manufacturing process involves inert gas atomization of powder, 3D CAD capsule design, sheet metal capsule fabrication and densification by HIP in very large pressure vessels. Since 1985, several thousand tonnes of parts have been produced. The major applications are found in the oil and gas industry especially in offshore applications, the industrial power generation industry, and traditional engineering industries. Typically, the components replace castings, forgings and fabricated parts and are produced in high alloy grades such as martensitic steels, austenitic stainless steels, duplex (ferritic/austenitic) stainless steels and nickel based superalloys. The application of PM/HIP near net shapes to pump barrels for medium to high pressure use has a number of advantages compared to the traditional forging and welding approach. First, the need for machining of the components is reduced to a minimum and welding during final assembly is reduced substantially. Mechanical properties of the PM/HIP parts are isotropic and equal to the best forged properties in the flow direction. This derives from the fine microstructure using powder powder and the uniform structure from the HIP process. Furthermore, when using the PM HIP process the parts are produced near net shape with supports, nozzles and flanges integrated. This significantly reduces manufacturing lead-time and gives greater design flexibility which improves cost for the final component. The PM HIP near net shape route has received approval from ASTM, NACE and API for specific steel, stainless steel and nickel base alloys. This paper reviews the manufacturing sequence for PM near net shapes and discusses the details of several successful applications. The application of the PM/HIP process to high pressure pump barrels is highlighted.

Abstract:
Abstract. Requirements of multi-material construction involve adjustments to standard joining techniques. Especially the growing importance of integral cast components poses additional engineering challenges for the industry. One approach to achieve these goals are adaptable joining elements formed by friction spinning. This approach uses friction-induced heat to form customisable joining elements to join sheets for different boundary conditions, even for brittle cast materials. It is possible to react immediately to adapt to the joining process inline and reduce the amount of different joining elements. As the joining partner serve casting plates of the aluminium casting alloy EN AC–AlSi9, which is processed in the sand casting. Joining hypoeutectic AlSi alloys constitutes a challenge because the brittle character of these cause cracks in the joint during conventional mechanical joining. Furthermore, the friction-induced heat of the novel joining process causes a finer microstructure in the hypoeutectic AlSi9 casting alloy. In particular, the eutectic Si is more fine-grained, resulting in higher joint ductility. This study indicates the joining suitability of a hypoeutectic aluminium casting alloy in combination with adaptive manufactured additional joining elements. Here, various mechanical and microstructural investigations validate the influence of the thermomechanical joining technique. In conclusion, the potential of this joining process is presented regarding the joinability of cast aluminium components.
