ARC MELTING, WORKING AND PROPERTIES OF TUNGSTEN + 0.6 COLUMBIUM ALLOY.

Abstract

Influence of small additions of carbon, oxygen, titanium and zirconium in tungsten +0.6% columbium alloy were studied. Arc melting, extrusion, forging, and swaging behavior are described. Elevated temperature tensile strength was correlated with annealing response of various wrought forms. Titanium and oxygen additions coarsened the cast structure and lowered the 3000 F tensile strength of the base composition. Zirconium increased 3000 F ultimate tensile strength approximately 10,000 psi in the swaged condition and 4000 psi in the fully annealed condition. (Author)
