Formation and Superconductive Properties of Amorphous and Metastable Zr-Mo-Ru AND Zr-Mo-Pd Alloys

Abstract

This study concerns with experimental investigations performed on the formation of a number of binary and ternary alloys based on Zr-Mo. Rapid solidification (splat cooling) of binary Zr-Mo resulted in metastable bcc structure materials while amorphicity was found in a restricted region of Zr-Mo-Pd and Zr-Mo-Ru ternary alloys. In the binary Zr-Mo materials investigated, superconductive transition temperatures near 4.7 K were observed; T c values for the amorphous ternary alloys are reported as well. Processing of Zr-Mo metallic powders by mechanical alloying resulting in the formation of supersaturated, Mo-rich bcc solutions.
