Ball milling can be used for “mechanical alloying” of powders, either to form compounds (e.g. formation of tungsten carbide from WO 3 + C or from W + C by direct carburization ) or to reduce the particle, crystallite, and grain size of an existing powder (e.g. formation of nanostructured WC-Co powders [8,9]).

These metal carbides are usually added during the mixing and milling of the tungsten carbide powder together with the metal binder, although vanadium carbide and chromium carbide can also be formed when carburizing the tungsten carbide powder. Grades of tungsten carbide powder can also be produced from recycled solid carbide materials.
