Promising V - Ti -(Nb, Ta, Mo, W) sheet alloys are being investigated since varadium-base materials exhibit an excellent combination of fabricability and elevatedtemperature strength. Tensile testing has been extended to 2000 deg F (1090 deg C). Specimens were protected by an inert atmosphere at the elevated temperatures because of lack of oxidation resistance. The V-5 Ti-20 wt.% Nb alloy exhibits tensile strengths of about 70,000 and 47,000 psi at 1800 and 2000 deg F, respectively. Trends indicate that further improvement by alloying is likely and that vanadium alloys may retain useful tensile strengths to higher temperatures. (auth)
