Solid solution and dispersion-strengthened vanadiumbase alloys were evaluated for use at temperatures in the 1200 deg to 2200 deg F range. The alloy V--1 wt% Hf --60 wt% Nb exhibited an ultimate tensile strength of 44,000 psi at 2200 deg F. Good strength at 2200 deg F was also observed for a V--1 wt% Ti--60 wt% Nb--5 wt% W composition. At 2000 deg F, the V--1 wt% Ti--60 wt% Nb-- 0.025 wt% C alloy withstood a stress of 10,000 psi for 25 hours. A portion of a 3-inch dismeter extruded bar of V --5 wt% Ti --20 wt% Nb was rendered to excellent quality 0.050 inch thick sheet by hammer forging followed by warm and cold rolling. (auth)
