Powder metallurgy science of manufacturing metal powders and making finished. Steps in powder metallurgy: Powder production, Compaction, Sintering, & Secondary operations. Metallurgy is that the primary solid-state synthesis technique utilized in the fabrication of both particle and whisker-reinforced MMCs. It involves blending of prealloyed or elemental powder of the matrix with ceramic whiskers or particulates and consolidation by die compaction, canning, powder forging or extrusion. In some cases, hot pressing or hot isotactic pressing (HIP) is additionally employed. Several commercial manufacturers like ALCOA and Advanced Composite Materials Inc. have used powder consolidation technology to fabricate sort of composites. The advantage of the PM technique is that high-quality, near-net-shape, and homogeneous parts are often made with substantially reduced machining and scrap. The near-net-shape PM method can make various TiAl components with complex shapes. Dimensions of the ultimate components are calculated supported the finite element modelling of powder shrinkage during HIP. This system has matured to a state of designing and making aerospace components with high precision. Metallurgy (PM) forging may be a process whereby a sintered powder metal part is forged employing a conventional closed-die forging to achieve the ultimate shape. One among the recent developments within the field of medical implants is production of porous metallic implants using the above-mentioned process using Co-based alloys or Ti-based alloys.
