A method for forming intermetallic and intermetallic-type precursor alloys for subsequent mechanical alloying applications. Elemental powders Are blended in proportions approximately equal to their respective intermetallic compounds. Heating of the blent results in the formation of intermetallic compounds whereas lack of heating results in intermetallic-type powder without the intermetallic structure. The resultant powder is then blended to form a final alloy. Examples involving aluminum-titanium alloys are discussed.
