An Overview of Mechanical Alloying and Conventional Metallurgical Methods

Mechanical alloying (MA) is a powder processing technique that involves the cyclic process of cold welding, fracturing, and rewelding of powder particles within a high-energy ball mill. This method has the ability to create several forms of non-equilibrium phases, such as supersaturated solid solutions, nanocrystalline materials, metallic glasses, high-entropy alloys, and more. Materials with shape memory properties have been utilized in various applications. This article enlightens on MA and other conventional metallurgical methods. The article provides a description of the current and future applications of MA.
