Abstract

The fabrication of two tantalum alloys—Ta-10Hf-5W and Ta-30Cb-7.5V—into sheet bar by extrusion, forging, and rolling is investigated and evaluated. The properties of the resulting sheet—especially its tensile properties and bend and weld ductility—are reported. Indications that sound fusion welds in the Ta-Cb-V alloy cause no appreciable loss in strength or ductility are given.
