Abstract:

Vanadium-niobium alloys prepared as 200-gram arc-melted ingots were evaluated for fabricability and tensile properties to 2400 F. Of the high-vanadium compositions, the strongest was V-5 wt-, Ti-20 wt-, Nb-10 wt-, Ta which had strength values of 54,000 and 15,700 psi at 2000 and 2400 F, respectively. Tensile values of the stronger alloys at the 60 wt- Nb levels were near 65,000 psi at 2000 F and near 20,000 psi at 2400 F. Strengthening of the V-Nb alloy bases was accomplished by addition of refractory metals Ta, W, the reactive metals Ti, Zr, Hf, and the interstitials C, O, N. Material from the first 100-pound double consumable-electrode arc-melted ingot, a V-1 wt-, Ti-60 wt-, Nb composition, was distributed to the organizations participating in the data exchange program. A second 100-pound ingot, V-4 wt-, Ti-20 wt-, Nb-1 wt-, Ti-0.75 wt-, C, was triple-melted and forwarded to a commercial source for extrusion and subsequent fabrication to bar, plate, and sheet.
