DEVELOPMENT OF A DUCTILE TUNGSTEN SHEET ALLOY

Abstract

Binary alloys of W with ThO2, ZrO2, and the Group VII and VIII metals are being evaluated to determine the effects of these additions on lowering the ductile-to-brittle transition temperature of W. Both powder-metallurgy and arc-melting techniques are being used in alloy preparation. A series of arc-melted binary alloys showed minima exist in the hardness curves of most binary systems of W with the Group VII and VIII metals. The greatest softening effects were found in the binary alloys containing 5 at.-% Re and 1 at.-% Os. (Author)
