ABSTRACT:
Alloys are produced from an elongated metal bar comprising a substantially pure majority metal by attaching a length series of surface patches thereto made of compacted powder mixtures of minority alloying elements and the majority metal, then progressively melting the bar along its length to produce a compositionally uniform alloy melt and solidifying the melt to produce an alloy ingot. The process results in ingots of uniform composition consistent with use of relatively volatile minority alloying elements.
