Noble metal medium entropy alloy (MEA) thin films have recently attracted enormous research interests recently because of their great potential in the catalytic application. . However, conventional bottom-up fabrication . We are developing a new freeform fabrication method named 3D micro welding (3DMW) to achieve freeforming metals and intermetallic alloys in micro-scale. It is a combined process of the freeform fabrication method, tungsten inert gas (TIG) welding, rapid prototyping (RP) and self-propagating high temperature synthesis (SHS).Nanoarchitectured mesoporous metal alloy films offer immense potential by integrating the intrinsic catalytic capabilities of their constituent metals to create suitable surface morphologies, different signal transductions and catalytic phenomena. These unique properties and functionalities have led to the d

1. Introduction. Electrochemical finishing of metals and alloys is widely used for chemical and structural modification of the surface [1].The result of the electrochemical treatment is dependent on (i) the electrolyte nature (aqueous solutions, mixtures of organic solvents with strong electrolytes, ionic liquids (ILs)), (ii) properties and composition of the liquid phase . This paper emphasizes a summary of work on Fabrication of Aluminum and its alloy Metal Matrix Composites reinforced with different typical Ceramic powder materials. Today Aluminum and its alloys Metal Matrix composites have prominent demand in the Automobile, Aerospace and Nuclear industry due to its physical and mechanical properties .Fabrication of metals and alloys Four basic manufacturing processes: Casting –to give a shape by pouring in liquid metal into a mold that holds the required shape, and letting harden the metal without external pressure. Forming –to give shape in solid state by applying pressure.• Al Alloys lower r: 2.7g/cm3-Cu, Mg, Si, Mn, Zn additions -solid solutions or precipitation strengthened (structural aircraft parts & packaging) -very low r: 1.7g/cm3-ignites easily - aircraft, missiles • Refractory metals-high melting T -Nb, Mo, W, Ta • Noble metals -Ag, Au, Pt - oxidation/corrosion resistant • Ti Alloys

As they were lighter than noble metal alloys, while still having corrosion resistance and excellent mechanical properties, they began to be used more frequently for removable partial dentures. . 3.7.2 Milling of Co–Cr Dental Alloys. Fabricating Co–Cr dental frameworks with conventional casting methods is challenging, due to the alloy`s .
Titanium and its alloys are suitable for biomedical applications owing to their good mechanical properties and biocompatibility. Beta-type Ti–Mn alloys (8–17 mass% Mn) were fabricated by metal injection molding (MIM) as a potential low cost material for use in biomedical applications. The microstructures and mechanical properties of the alloys were evaluated. Thus, alloy fabrication takes shape so that one can get enhanced property materials. At the earlier stages of metallurgy, the development of alloys contains one principal element as a matrix. . It is the fabrication process of metal matrix composite (MMC) in which dispersion phase particles diffuse with the matrix phase of composite in a . We are developing a new freeform fabrication method named 3D micro welding (3DMW) to achieve freeforming metals and intermetallic alloys in micro-scale. It is a combined process of the freeform fabrication method, tungsten inert gas (TIG) welding, rapid prototyping (RP) and self-propagating high temperature synthesis (SHS).The purpose of this study is to investigate the effect of the fabrication method of dental prosthesis on the mechanical properties. Casting was produced using the lost wax casting method, and milling was designed using a CAD/CAM program. . Co–Cr alloys are non-precious metal alloys that are developed as a substitute for gold alloys, and .
Mujtaba Ashraf 95 Conclusion It is not always possible or feasible to use noble or precious metals and alloys for fabrication of restorations. Moreover, most removable partial dentures are fabricated from chrome-cobalt .

Multi-component ingots of about 15 g were prepared by arc melting mixtures of hot metal, ferro-alloys and pure elements of commercial grade (>95%) under a Ti gettered argon atmosphere.The chemical compositions of hot metal and ferro-alloys are shown in Table 1 (in mass%). The ingots were re-melted several times to ensure compositional homogeneity and . fabrication, the aluminium cast alloy is widely preferred as a metal matrix for its unique properties, and di ff erent reinforcements are employed in the form of oxides, carbides, and nitrides. In dentistry, base metal casting alloys are extensively used for the fabrication of inlays, onlays, crowns, bridges, partial dentures, etc. During the casting of these alloys, excess amount of material used than needed will be collected as sprue buttons at the end, which is either added to the fresh alloy during casting and reused or disposed of.
A great variety of alloys is used in production of metal infrastructures for metal–ceramic FPDs, with the greatest application being the noble, Ni–Cr and Co–Cr alloys. The high cost of the noble elements and the allergenicity of Ni are the main reasons that determine Co–Cr alloys as main choice for fabrication of metal–ceramic FPDs.
