Promising V-Ti (Nb. Mo, Ta, W) alloys are being investigated since vanadium-base alloys exhibit excellent elevated temperature strength. Fabrication of the arccast "pancake" ingots to 0.050 in. thick sheet was performed by cold rolling. Only one intermediate anneal was required for the V- 5 wt. ~ Ti--20 wt. % Nb composition. Tensile testing was conducted at room temperature and 2000 deg F. Specimens were protected by an inert atmosphere at elevated temperatures to protect against oxidation. Several V- Zr- Nb and V- Hf- Nb alloys were evaluated, but results to date do not show improvement over the V- Ti-Nb system. The V-60 wt. % Nb alloy exhibits a tensile strength of 63,500 psi at 2000 deg F. (auth)
