Mechanical alloying (MA) is a nonequilibrium alloying process with which various unstable or metastable materials, such as highly supersaturated solid solutions, amorphous alloys and intermetallic compounds, can be prepared. Although MA has been applied most extensively to alloying between solid elements, it is also an effective means for allying gaseous elements by solid-gas reactions. In particular, nitrogen can be alloyed up to very high concentrations with nitride-forming transition metals and their alloys by ball milling their powders in nitrogen gas. In the present study, the authors applied this new nitriding technique to the preparation of TiN and a solid solution nitride (Ti, Al)N, and examined the nitriding kinetics and thermal stabilities of the nitrides.
