Abstract:

One of the key application areas of Single Point Incremental Forming is in the manufacture of parts for bio-medical applications. This paper discusses the challenges associated with the manufacture of cranio-facial implants with extreme forming angles using medical grade titanium sheets. While on one hand, the failure wall angle is an issue of concern, the parts also need to be manufactured with accuracy at the edges where the implants fit into the human body. Systematic steps taken to overcome these challenges, using intelligent intermediate part design, feature analysis and compensation, are discussed. A number of case studies illustrating the manufacture of accurate parts in aluminium, stainless steel and titanium grade-2 alloy are discussed.

Abstract:

The laser build-up cladding is a well-known technique for additive manufacturing tasks. Modern equipment for the laser cladding enables material to be deposited with the lateral resolution of about 100 μm and to manufacture miniature parts. In this paper the laser micro cladding process was investigated to produce miniature thin-wall parts of Al-based composites. Thin walls formation process by subsequent single tracks overlapping with vertical increment was investigated. The influence of the cladding parameters on the minimal width and the quality of the fabricated thin walls was examined. The thin walls with the minimal width of 140 μm and surface roughness Ra 1,5 μm were generated. Laser micro cladding potential to manufacture lattice-shaped structures of Al-Si composites was shown. Fabricated thin-wall structures can have application in different fields e.g. aviation, automotive and tooling industries.

Abstract:

AbstractAs a widely used additive manufacturing technique, the laser metal deposition process (LMD) also known as direct energy deposition (DED) is often used to manufacture large-scale parts. Advantages of the LMD process are the high build-up rate as well as its nearly limitless build-up volume. To manufacture large-scale parts in lightweight design with high strength aluminium alloy EN AW-7075, the LMD process has a disadvantage that must be considered. During the process, the aluminium alloy is melted and has therefore a high solubility for hydrogen. As soon as the melt pool solidifies again, the hydrogen cannot escape the melt and hydrogen pores are formed which weakens the mechanical properties of the manufactured part. To counter this disadvantage, the hydrogen must be successfully kept away from the process zone. Therefore, the covering of the process zone with shielding gas can be improved by an additional shielding gas shroud. Furthermore, the process parameters energy input per unit length as well as the horizontal overlapping between two single tracks can be varied to minimize the pore volume. Best results can be achieved in single tracks with an elevated energy input per unit length from 3000 to 6000 J/cm. To manufacture layers, a minimal horizontal overlapping will lead to lowest pore volume, although this results in a very wavy surface, as a compromise of low pore volume and a nearly even surface a horizontal overlapping of 30 to 37% leads to a pore volume of 0.95% ± 0.50%.

Abstract:

Metal powder is the main raw material in the manufacture of powder metallurgy-based products. Powder-making is the initial step before the powder is packed and pressed in a mold to form the desired product. This research designs and fabricates an atomizer to produce powder from liquid aluminum using a pressurized water jet system. The research stage starts from the drawing of the tool design by considering the volume of liquid aluminum, the diameter of the outlet of liquid metal, the air pressure, and the angle of attack of the water beam. The second stage is the manufacture of the atomization chamber by referring to the design drawing by making parts of the tool/frame, liquid metal feeder parts, making the walls of metal plates, making the nozzle holder, and collecting the powder parts and the water exhaust channel. The third stage is assembly, which is to unite the main parts of the aluminum atomizer. The final stage is the testing of the atomization tool using 250 Psi pressurized water with variations of attack angle was 30˚, 35˚, 40˚, 45˚, and 50˚ with a metal descending channel diameter of 5 mm. The results showed that the 45o spray angle gave the highest percentage of powder amount and the lowest 40o angle resulted in the size of aluminum metal powder in the range 0.105 mm-0.5 mm. The size of the powder was obtained at an angle of attack of 35o, which is an average of 39.5 um, and the largest size of powder was obtained at a spray angle of 40o of 89.5 um. The resulting powder form is irregular in shape, flakes (flakes), spheroid (spherical), and spongy (hollow).

Abstract:

The life cycle holistic approach for the automotive sector highlighted how much important is working on decarbonisation of Al casting processes to produce vehicle components. Broadening the use of recycled aluminium alloys, instead of high energy intensive primary aluminium alloys, is key for environment preservation. While primary aluminium alloys are preferred by automotive original equipment manufacturers (OEMs) because impurities (mainly Fe) present in secondary aluminium alloys might cause fatigue properties decay, a new semisolid state process route has been developed at Brembo to drastically reduce the sensitivity of cast aluminium to Fe impurities. Based on these premises, during the CRAL European project in the framework of the LIFE Programme, an industrial prototype machinery - a vertical high pressure die casting machine - has been designed and constructed to inject secondary aluminium in the semisolid state. A number of A357 Fe-enriched brake callipers manufactured via the new process route have been fully investigated by fatigue tests, SEM and OM analyses in order to validate the new eco-sustainable product compared to conventional ones manufactured with primary aluminium by gravity casting.

Abstract:

Compound forging is a technology to successfully manufacture hybrid parts by applying resource-saving process steps. During compound forging of steel-aluminum parts the formation of intermetallic phases is benefited. The thickness of these intermetallic phases influences the bonding and thus the global part quality. According to literature, specific coating elements reduce the phase seam thickness. In powder-metallurgically manufactured parts it is possible to selectively insert specific elements in the surface area. Therefore, a time intensive coating process can be avoided. The applicability of combining the technologies of powder-metallurgy and compound forging is discussed in this paper. Powder-metallurgically manufactured and solid parts made of steel and aluminum are compound forged and the influences on deformation behavior and the joining zone are investigated.

Abstract:

Selective laser melting (SLM) is a powder bed fusion type metal additive manufacturing process which is being applied to manufacture highly customised and value-added parts in biomedical, defence, aerospace, and automotive industries. Aluminium alloy is one of the widely used metals in manufacturing parts in SLM in these sectors due to its light weight, high strength, and corrosion resistance properties. Parts used in such applications can be subjected to severe dynamic loadings and high temperature conditions in service. It is important to understand the mechanical response of such products produced by SLM under different loading and operating conditions. This paper presents a comprehensive review of the latest research carried out in understanding the mechanical properties of aluminium alloys processed by SLM under static, dynamic, different build orientations, and heat treatment conditions with the aim of identifying research gaps and future research directions.

Abstract:

As several of the free form fabrication processes progress with continuous process and material improvements, the feasibility of Rapid Manufacturing becomes more and more of a reality. Defined as the use of a Computer Aided Design (CAD) based automated additive manufacturing process to construct parts that are used directly as finished products and components, some of the rapid manufacturing processes are already competing with traditional processes such as injection moulding and progress is being made in applying the new technologies to the processing of metals, envisioning additive manufacture of high strength parts of unlimited complexity. While there have been quite a few successful attempts in the rapid production of complex medical implants using titanium alloys, 3D printing of sand moulds opens up yet another rapid manufacturing front, allowing for the rapid casting of aluminium and magnesium alloys. The effectiveness of such processes is yet to be researched in terms of process and product characteristics and the overall economy. This paper attempts to review some of the promising rapid manufacturing technologies for light metals processing and presents results of experimental investigations conducted to evaluate the effectiveness of the rapid casting process currently researched at the Rapid Product Development Centre of AUT University.

Abstract:

Aeronautic parts have generally complex structure and need high mechanical properties. Machining is an essential step to manufacture aluminium alloy aeronautical parts. To obtain parts complying with geometrical specifications, the machining process must be well understood and mastered. Indeed, many factors may induce geometrical deflections during the machining process. On large aeronautical parts, the main factor which can lead to non-complying part is the unexpected release of original residual stresses. In this work, a specific finite element solver has been developed to predict the distortion due to the redistribution of the original residual stresses during machining. Then, results obtained are compared with experimental tests to validate this approach.

Abstract:

Saab Surveillance in Järfä̈lla constructs complex products, such as radars and electronic support measures. Saab sees an advantage in manufacturing details with additive manufacturing as it enables a high level of complexity. Additive manufacturing is relatively new in the industry and consequently there are uncertainties regarding the process. The purpose of this bachelor thesis was to improve the knowledge of the repeatability of additive manufactured parts as well as compare additive manufactured test rods in two different directions, horizontally and vertically, to subtractive manufactured test rods with a vibration test. The vibration test was conducted to simulate the operative environment where the additive manufactured parts might be implemented in the future. Before the vibration test could be performed, the test rods were designed in a 3D-modeling program and analysed with a finite element method to achieve the required natural frequency range of 100 - 200 Hz and a maximal bending stress of 60 - 80 MPa in the notched area of the test rod. It was concluded that the subtractive manufactured test rods had the highest repeatability. The horizontally additive manufactured test rods had a higher repeatability than the vertically additive manufactured test rods, but the vertically additive manufactured test rods had the highest overall strength. It was also concluded that more studies are needed to ensure that additive manufactured parts can be produced with high repeatability while maintaining the structural integrity.
Saab Surveillance i Järfä̈lla konstruerar komplexa försvarsprodukter som till exempel radarsystem. Additiv tillverkning i metall möjliggör tillverkning av produkter med hög komplexitet, men då tillverkningsprocessen är relativt ny i industrin finns det en stor osäkerhet kring processen. Syftet med detta kandidatexamensarbete var att få en bättre förståelse för repeterbarheten hos additivt tillverkade delar samt att jämföra additivt tillverkade provstavar konstruerade i två olika riktningar, horisontellt och vertikalt, med svarvade provstavar med hjälp av ett vibrationstest. Vibrationstestet genomfördes för att simulera den operativa miljön där de additivt tillverkade detaljerna skulle kunna implementeras i framtiden. Innan vibrationstestet kunde utföras simulerades provstavarnas design i en mjukvara för 3D-modellering. En finit element-analys utfördes även fö̈r att få en egenfrekvens inom intervallet 100 - 200 Hz och en maximal böjspänning mellan 60 - 80 MPa i anvisningen på provstaven. Slutsatsen drogs att de traditionellt bearbetade stavarna hade den högsta repeterbarheten. De horisontellt additivt tillverkade stavarna hade högre repeterbarhet än de vertikalt additivt tillverkade stavarna, men att de vertikalt additivt tillverkade stavarna hade ett längre utmattningsliv. Det kunde även konstateras att fler studier inom ämnet behövs för att kunna säkerställa repeterbarheten hos additivt tillverkade delar utan att behöva kompromissa med hållfastheten.

Abstract:

This study identifies the concepts of reliability, cost of downtime, cost of spare parts, and procurement lead time as the four key moderators of spare parts availability. These concepts are used to establish a model to manage spare parts inventories. Reliability was assessed in terms of developing failure predictions for major component categories. Cost of downtime was evaluated by identifying various methods for determining costs associated with downtime. Cost of spare parts was examined to find correlations with economic indicators. These correlations were used to predict future price movements. Yearly changes in lead time were identified and correlated with economic indexes to develop movement predictability.

Abstract:

Additive manufacturing of aluminium alloys using selective laser melting (SLM) is of research interest nowadays because of its potential benefits in industry sectors such as aerospace and automotive. However, in order to demonstrate the credibility of aluminium SLM for industrial needs, a comprehensive understanding of the interrelation between the process parameters, produced microstructure, and mechanical behaviour is still needed. This thesis aims at contributing to developing this comprehensive understanding through studying the various aspects of the process, with investigation of the powder raw material to the near fully dense samples, focussing on the alloy AlSi10Mg. The primary building blocks in the SLM process are the single tracks. Their formation is affected by the physical properties of the material that control the laser-material interactions. Keyhole mode melting was found to be dominant when processing AlSi10Mg, producing conical-shaped melt pools. Porosity was not evident in single tracks and individual layers. Satellites and balling defects, however, were observed on top of the tracks and layers at higher scan speeds, which contribute to porosity formation with layer progression. The combination of process parameters controls the amount of porosity formed, with the scan speed controlling the type of pore; metallurgical or keyhole pore. A pre-melt scan strategy significantly reduced porosity and successfully produced 99.8% dense samples. Furthermore, the pre-melt scan strategy was seen to effectively reduce the number of pores developed when using powder that does not fully comply with the process standards. The gas flow rate within the process chamber controlled laser spatter and condensate removal during processing, which in its turn affected the degree of porosity in the samples. The SLM process resulted in an AlSi10Mg alloy with a characteristically fine microstructure, with fine equiaxed grains at the melt pool core and coarser elongated grains at the boundary. The material showed a strong texture, owing to directional solidification. Cellular dendritic Al with inter-dendritic Si was observed. The material was subjected to a T6 heat treatment that transformed the microstructure into spheroids of Si in the Al matrix. This study investigated, for the first time, the local mechanical properties within the SLM material using nanoindentation. This showed a uniform nano-hardness profile that was attributed to the fine microstructure and good dispersion of the alloying elements. Spatial variation within the material was recorded after the T6 heat treatment due to phase transformation. This study is also the first to report on the compressive behaviour of solid SLM material, which is important for developing prediction and simulation models. The heat treatment softened the material and provided it with an increased ductility under indentation, tensile, and compressive types of loading. In addition, the material showed good fatigue performance, which was further improved by heat treatment and machining to obtain a smoother surface roughness. This investigation has, therefore, developed an understanding of the various aspects of the SLM process yielding near fully dense parts and defined the microstructure-mechanical property interrelation promoting the process for Al alloys in a number of industrial sectors.

Abstract:

To manufacture a high precision component, the aircraft industry in particular, employs computer numerical control machining to produce the aircraft components. However, it has often been found that problems of distortion occur when thin and slender components are manufactured this way. It is believed that the distortion arises due to the re-distribution of the residual stress field that was present in the original component in addition to the effects of cutting forces and temperatures that were induced during the machining process. At present, the process to produce a component with acceptable tolerance limits is one of trial and error. This often consumes a lot of time and produces considerable material wastage. The finite element method has been used to develop a methodology to model the actual machining process that produced the aircraft component. The finite element model that has been developed so far was able to demonstrate the effects of redistribution of the residual stresses on the distortion of the final machined component. It was found that the final component distorted differently when the materials were simply removed from a solid billet with different material removal sequences. A preliminary investigation on the effects of cutting temperature and forces has also been made. The investigation showed that such effects could not be totally ignored as they significantly affect the distortion of the final component. In addition to modelling the machining process, a methodology has also been developed to introduce and simulate the clamps and machine worktable that are part of the machining process. Although there is a considerable amount of work relating to modelling machining processes, there has not been any previous attempt to address the problem as a whole as described in this thesis. It is hope that the work undertaken here would be able to provide a stepping-stone to such attempts in future. However, further experimental data would be required to complement a more refined model in the attempt to accurately predict the distortion in machined components. It is believed that it would be possible to then extend the developed methodology to minimise the distortion by changing the machining sequence and the shape of the material to be removed. This would reduce the timescales involved to correct the problems of distortion and eliminate material wastage.

Abstract:

Rapid manufacture refers to those processes in which a component can be manufactured without the need for specific tooling. This reduces the time between the design stage and production of finished parts compared with traditional methods such as forging or casting. There are a number of laser based rapid manufacture processes currently available such as selective laser sintering and direct laser deposition which are both based on adding powder form material to a substrate in a layer-by-Iayer fashion. Subtractive methods such as laser milling have been developed to a lesser extent but are lirriited by low removal rates and problems caused by heat affected zones. Here, three new subtractive methods of laser rapid manufacture of near net shape titanium components were developed. Each was investigated and the most promising was chosen for further research. The chosen method is based on water assisted laser processing of partially sintered titanium powder. A block is made by partial sintering of titanium powder in a furnace such that it has the properties of being strong enough to be handled but still porous, with the powder particles retaining their spherical shape. The block is then soaked in liquid so that the interconnected pores become filled. A laser is used to irradiate the surface of the block which causes material removal from the irradiation site in a predictable way. The process was characterised by investigating the influence of process parameters: sintering temperature, laser energy density, powder particle size, laser repetition rate and type of liquid used to soak the blocks. The process was also analysed using high- . speed photography, emission spectroscopy and the probe-beam extinction technique to gain an understanding of the material removal mechanism. A computational model of the process was proposed based on the Smoothed Particle Hydrodynamics method. It was found that the mechanism of material removal is based on the explosive boiling of the liquid in the pores of the partially sintered block caused by heating from the laser. The rapid expansion of the exploding water creates a pressure which breaks the weak bonds between particles and ejects them from the surface. The new method can be faster than the current additive laser based rapid manufacture techniques and uses lower laser powers than the current laser milling processes. This is achieved through the choice of experimental conditions and laser parameters.

Abstract:

Today, high levels of precision and accuracy are needed in manufacturing to meet the increased complexities in product designs. Most products consist of multiple assembled parts, and fitting these parts together can present a major challenge, especially for complex products. Thus manufacturing with high precision is particularly required, and CNC machining is typically used as a machining process to reduce the risk of parts not fitting together in the assembly process, especially for automatic assembly. Thereby improving quality control and reducing scrap in high-value and low volume production. Over the last 60 years, NC and CNC machines have been used to improve product quality due to their increased accuracy. However, even with today’s more sophisticated machine tools, errors still occur during machining. The literature shows that there are numerous sources of error in machining processes. Additionally, different methods are being used to define and subsequently correct these errors. The methods used to compensate these errors typically depend on offline error compensation. A gap in the existing research methods has been identified as a lack of online error compensation methods to enable parts to be manufactured to specification and corrected during the machining process. The major contribution of this research is the design and implementation of a method for production of right-first-time parts based on an online error compensation. The proposed framework, CLosEd loop MAchining and inspecTIon System (CLeMatiS), is considered to be an important approach for industry to improve the machining and measuring accuracy for high-cost parts. A computational model has been developed, where an algorithm within this model can handle different types of feature relationships and is able to update feature positions based on on-machine measurements. This research shows that the proposed method for compensating the machining errors in order to machine parts right-first-time provides advantages over traditional methods. The method thus improves the positional accuracy of machined features while maintain the relationships between them, compared to the traditional machining.

Abstract:

Abstract Forming processes are a convenient means for bulk production of parts. These parts are used in a wide range of applications from automotive industries to micro-devices in bioengineering. Manufactured parts are required to be precise in their final dimension, and since the billet material undergoes significant plastic deformation during forming, billet material characterization and prediction of final form is essential. In this study, miniaturized bowl-shaped samples of 3003-H14 aluminum alloy were formed using a die and punch manufactured using the stereolithography (SLA) additive manufacturing method. Tensile testing was performed in order to characterize the material properties of the SLA resin. Using the SLA-created die and punch, hemispherical bowl-shaped forms were generated. In order to investigate possible small size effects, experimental load versus displacement results were obtained for billet plate thicknesses of 0.4–0.8 mm. A numerical finite element model was developed to predict the required punch load to manufacture various thickness bowl-shaped forms. A comparison was made between the load verses displacement curves for the different thicknesses, and the numerical model was validated by the experimental results. The validated computational model can then be used to predict the process parameters prior to starting bulk production. Finally, a model with grains was developed and simulated to show the virtual microstructural morphology of the circular plates before and after the forming operation.

Abstract:

Due to more stringent environmental regulations, the demand for strong, lightweight metal alloys, such as AA 5083, has increased. In sheet metal forming, aluminum is preferred over higher density steels to manufacture such parts; however the in-plane anisotropic behavior of AA 5083 alloy greatly affects its formability. Previous researchers have found that mechanical properties of metallic materials can be influenced by DC electrical current, a research area known as Electrically-Assisted Manufacturing (EAM). The research herein is focused on characterizing the in-plane anisotropic behavior of AA 5083 alloy with and without DC current application, while it is loaded in the uniaxial direction. Furthermore, the effects of EAM on Lueder’s banding will also be investigated.

Abstract:

Ferritic-austenitic (duplex) stainless steel components are used for oil and gas production duties due to their high strength and corrosion resistance. The material is routinely used for short flowlines, as well as for welded hubs and flanges. Cathodic protection (CP) is employed, via sacrificial aluminium based anodes, which protects ferritic steel parts from seawater corrosion. Whilst CP has proven successful in preventing corrosion, failures have occurred due to the ingress of electrolytically evolved hydrogen. Duplex stainless steel joints become susceptible to environmental cracking under a combination of high stress, hydrogen content, and susceptible microstructures; critical combinations of which may result in hydrogen induced stress cracking (HISC). Successful operation of duplex equipment, in avoidance of HISC, necessitates a good understanding of the total in-service stresses (including from loading applied in service and from residual stresses from manufacture, fabrication, installation and commissioning). One of the key components of understanding the in-service stress at welds is knowledge of the residual stress distribution, following welding. The focus of this paper is to provide an overview of the typical residual stress levels in a welded superduplex stainless steel (SDSS) subsea joint, using neutron diffraction and finite element modelling. The results are presented in the context of current recommended practice, for example DNV RP-F112.

Abstract:

Three innovative extrusion processes for the manufacture of multi-material parts are discussed: co-extrusion of discontinuously steel reinforced aluminum profiles, composite extrusion of continuously steel wire reinforced profiles and composite rod extrusion. In the first two processes the embedded steel elements are not deformable while by composite rod extrusion both materials are deformable. By means of experimental and numerical analysis, the parameters that mainly influence the reinforcement ratio, the extrusion force as well as the material distribution are analyzed. On the basis of this, analytical approaches are deduced to describe the process limits for the technologies. The paper closes with examples of applications regarding the lightweight requirements as well as functional integrations by forming multi-materials.

Full text

Abstract:

The improvement of reliability and reduction of overhaul time is of paramount importance to engineers involved with coatings used on gas turbine engine components. Aluminum/phosphate/chromate coatings are currently used in industrial and aircraft gas turbine engines for coating compressor components. Traditional electrolytic nickel with diffused cadmium coatings are also used but to a lesser extent. Field experience, however, has shown limitations with both coating systems, particularly in the areas of erosion, wear, and simplicity in component processability. Currently, several new electroless nickel coatings are gaining significant acceptance in the industry, both for overhaul and repair, as well as for new part manufacture. This paper presents erosion, corrosion, fatigue and stress data on these coatings. Some field experience is also presented from airline operators and overhaul facilities who are incorporating these coatings on aircraft gas turbine engine components. Information is also given on the capability of electroless nickel coatings to reduce manufacturing cost and simplify the processing of complex parts.

Abstract:

Bent profiles are used in the manufacture of many kinds of products such as transport apparatus and mechanical parts for reduction of production cost and weight. The conventional processes for bent profiles involve a successive extrusion, stretching, and bending of the profiles. Conventional bending methods can not meet demands for precision and cost-effective production in some cases, due to cross sectional deformation, irregular decrease of tube wall thickness and a complication of the process design. There are some researches regarding bending of extruded aluminum profiles during the extrusion process. However, there is no study about the exact prediction of the final various curved profiles. This paper presents the achievements of control of bending tool in the curvature extrusion for a bent profile with various radii. A geometric model, which is the relationship between the bending tool velocity and the extrusion velocity, is proposed to predict the exact geometry of the various curved profile using FE simulation. Experiments were conducted to verify the effectiveness of the proposed geometric model for a vehicle bumper with the various outline radii from 1900mm to 2200mm. The overall correlation between experiments and theoretical results is good. It is, therefore, concluded that the present method provides an efficient means for the variable curvature extrusion process.

Abstract:

Chinese Spallation Neutron Source (CSNS) is a significant research facility for studies of structure and dynamics of materials, which can play an important role in research and education. Moderators and reflectors system is one of the core components in CSNS. There are three moderators totally, namely, the decoupled and poisoned hydrogen moderator, the coupled hydrogen moderator and the decoupled water moderator. Moderators are inserted into an aluminum alloy vessel which contains beryllium and stainless steel reflectors. The moderators and reflectors are designed into a whole plug, MR Plug, so as to move the plug into or out of the core vessel of CSNS easily. The structure design of moderators and reflectors system is just finished now, including moderators, reflectors and their container. Neutronics requirements and strength criterions are satisfied, manufacture of system is feasible. Structure strength analyses of some parts are also presented.

Abstract:

Abstract Maintenance, repair, and overhaul activities are necessary and critical, often repeated, operations which occur during the lifecycle of turbomachinery components and assemblies. The ability to extend the life and performance of parts via sustainment type activities currently in service offers a significant and beneficial financial impact for both the manufacturers of these components as well as their end-users. Additive manufacturing not only enables manufacturers the ability to “print” complex geometries in a wide array of materials including metals but, in some instances, also offers a novel opportunity for the repair and overhaul of existing components. The MELD process is quickly becoming an established AM technology which has repeated demonstrated success in additive manufacturing, repair, coating, and joining operations. The MELD process creates fully-dense products with near wrought properties, and reduced distortion, at very high deposition rates. MELD is a solid-state process, which yields parts with superior mechanical properties as compared to those produced by liquid-state metal deposition or spray forming processes. It is an open atmosphere process, allowing for extreme scalability. By the nature of the process all depositions, repairs, and coatings are fully dense and do not require any additional processing for densification such as sintering or HIP. Potential disadvantages include the inability to construct complex, finely featured products. The MELD process is well suited for the fabrication, repair, and overhauling of large-scale components as it is not restricted to space restrictive powder beds or vacuum chambers. In addition, the MELD process carries a lower operating cost (comparable to a CNC mill) and requires less infrastructure than traditional melt-based AM technologies. In this presentation, the MELD process will be explored as a viable method for additive manufacturing, coating, repair, and joining operations. Unique attributes will be considered along with resulting advantages and disadvantages. Specific high-level real-world examples presented will include MELD applications which highlight the repair of a cast non-fusion weldable Mg helicopter gearbox housing, the joining and repair operations of simulated damage (holes and cracks) using 2XXX and 7XXX series aluminum alloys, the application of nickel-based super-alloy coatings on high-strength low alloy steels, and the additive manufacture and repair of titanium alloys.

Brophy, Kenny, and Alison Sheridan, eds. Neolithic Scotland: ScARF Panel Report. Society of Antiquaries of Scotland, June 2012. http://dx.doi.org/10.9750/scarf.06.2012.196.

Full text

Abstract:

The main recommendations of the Panel report can be summarised as follows: The Overall Picture: more needs to be understood about the process of acculturation of indigenous communities; about the Atlantic, Breton strand of Neolithisation; about the ‘how and why’ of the spread of Grooved Ware use and its associated practices and traditions; and about reactions to Continental Beaker novelties which appeared from the 25th century. The Detailed Picture: Our understanding of developments in different parts of Scotland is very uneven, with Shetland and the north-west mainland being in particular need of targeted research. Also, here and elsewhere in Scotland, the chronology of developments needs to be clarified, especially as regards developments in the Hebrides. Lifeways and Lifestyles: Research needs to be directed towards filling the substantial gaps in our understanding of: i) subsistence strategies; ii) landscape use (including issues of population size and distribution); iii) environmental change and its consequences – and in particular issues of sea level rise, peat formation and woodland regeneration; and iv) the nature and organisation of the places where people lived; and to track changes over time in all of these. Material Culture and Use of Resources: In addition to fine-tuning our characterisation of material culture and resource use (and its changes over the course of the Neolithic), we need to apply a wider range of analytical approaches in order to discover more about manufacture and use.Some basic questions still need to be addressed (e.g. the chronology of felsite use in Shetland; what kind of pottery was in use, c 3000–2500, in areas where Grooved Ware was not used, etc.) and are outlined in the relevant section of the document. Our knowledge of organic artefacts is very limited, so research in waterlogged contexts is desirable. Identity, Society, Belief Systems: Basic questions about the organisation of society need to be addressed: are we dealing with communities that started out as egalitarian, but (in some regions) became socially differentiated? Can we identify acculturated indigenous people? How much mobility, and what kind of mobility, was there at different times during the Neolithic? And our chronology of certain monument types and key sites (including the Ring of Brodgar, despite its recent excavation) requires to be clarified, especially since we now know that certain types of monument (including Clava cairns) were not built during the Neolithic. The way in which certain types of site (e.g. large palisaded enclosures) were used remains to be clarified. Research and methodological issues: There is still much ignorance of the results of past and current research, so more effective means of dissemination are required. Basic inventory information (e.g. the Scottish Human Remains Database) needs to be compiled, and Canmore and museum database information needs to be updated and expanded – and, where not already available online, placed online, preferably with a Scottish Neolithic e-hub that directs the enquirer to all the available sources of information. The Historic Scotland on-line radiocarbon date inventory needs to be resurrected and kept up to date. Under-used resources, including the rich aerial photography archive in the NMRS, need to have their potential fully exploited. Multi-disciplinary, collaborative research (and the application of GIS modelling to spatial data in order to process the results) is vital if we are to escape from the current ‘silo’ approach and address key research questions from a range of perspectives; and awareness of relevant research outside Scotland is essential if we are to avoid reinventing the wheel. Our perspective needs to encompass multi-scale approaches, so that ScARF Neolithic Panel Report iv developments within Scotland can be understood at a local, regional and wider level. Most importantly, the right questions need to be framed, and the right research strategies need to be developed, in order to extract the maximum amount of information about the Scottish Neolithic.
