Abstract

Homogeneous and refined microstructure powders and the method of making them from, for example, liquid metal immiscible systems or very limited solid solubility systems. At least two metals are melted and then rapidly solidified to yield a solid with a segregated, non-uniform microstructure. The resulting rapidly-solidified solid is then reduced to a powder and subjected to high-energy milling for a time sufficient to reduce the segregation to the desired level of uniformity.
