Abstract
Precursor alloys for subsequent mechanical alloying into a final alloy, pref. a Al 4% Ti alloy, are formed by: a) forming a first blend of the principal (I) and secondary (II) elements (Al and Ti respectively) in a proportion equivalent to the compsn. of an intermetallic cpd. formed by (I) and (II), the percentage of the secondary element in the precursor alloy is in excess of that in the final alloy; b) mechanically alloying the first blend; c) adding an additional quantity of the principal element to b), to raise the percentage of the element in the final alloy, to form a second blend; and d) mechanically alloying the second blend. Pref. the first blend is heated prior to mechanically alloying .
