Preparation and Properties of AlSb-GaSb Solid Solution Alloys

Abstract

Ingots of the quasi‐binary alloy were prepared by progressive casting and zone casting at various rates of crystallization. Results of x‐ray diffraction studies, metallographic studies, hardness determinations, and chemical analyses indicate that, with the possible exception of a narrow composition range between 10 and 30 mole % which was not investigated, solid solution prevails in the system. Bulk specimens of single phase, solid solution alloy were obtained by use of low linear rates of crystallization (0.05 in./hr), while at higher rates of crystallization (¼ to 1¼ in./hr) two intermingled solid phases were characteristically obtained.
