Powder Metallurgy Peer Review Journals

The powder-metallurgy (PM) process, depicted within the diagram below, involves mixing elemental or alloy powders, compacting the mixture during a die, then sintering, or heating, the resultant shapes in an atmosphere-controlled furnace to metallurgical bond the particles. Metal injection moulding (MIM) offers a producing capability for producing complex shapes in large quantities. The method utilizes fine metal powders that are custom-formulated with a binder (various thermoplastics, waxes, and other materials) into a feedstock. Isostatic pressing may be a PM forming process that applies equal pressure altogether directions on a compact, thus achieving maximum uniformity of density and microstructure without the geometrical limitations of uniaxial pressing. Metal additive manufacturing (AM), or 3D printing, has the potential to profoundly change the assembly, time-to-market, and ease of components and assemblies. Unlike conventional or subtractive manufacturing processes (e.g., drilling), which create a neighborhood by removing material, additive manufacturing builds a neighborhood employing a layer-by-layer process directly from a digital model. It doesn't use molds or dies that add time, waste, and expense to the manufacturing process. Additive manufacturing has been used as a design and prototyping tool for many years, but the main target of additive manufacturing is now shifting to the direct production of components, like medical implants, engine parts, and jewellery.
