OSTI ID:4177457
The workability and mechanical properties of a number of niobium-base alloys were evaluated. A Nb-5 n.% V-5 wt.% Mo-1 wt.% Zr alloy, tested in the fully recrystallized condition, had a 50,500 psi yield strength at 1093 deg C (2000 F). Preliminary data concerning the effect of oxygen on the mechanical properties of certain niobium base alloys were obtained. Oxygen additions appear to have a significant effect on the high temperature tensile properties of Nb-Hf and Nb-Ti-Zr-Hf alloys. Ternary phase diagram and welding studies continued. (For preceding period see NP-8392.) (auth)
