Mechanical Alloying an overview ScienceDirect Topics

Mechanical alloying was devised by Benjamin at the International Nickel Company to introduce hard particles, such as oxides and carbides, into a metallic matrix on a scale that is much finer than can be achieved by conventional powder metallurgy practices. The process involves the high-speed attrition of dry, elemental, or simple alloy powders in modified, high-energy ball mills.
