PILOT EVALUATION OF VANADIUM ALLOYS. Bimonthly Report No. 3, January 18, 1962-March 17, 1962
Compositions based upon V--1 wt% Ti--60 wt% Nb and V--1 wt% W--60 wt% Nb complexed with 0.05 to 0.l wt% oxygen and/or nitrogen were evaluated for fsbricability. The materials containing less than 0.06 wt% deliberate interstitial additions could be rendered to sheet by warm (1000 deg F) working; compositions with greater amounts could not be fabricated even by hot working in the temperature range of 1800 to 2400 deg F. Tensile evaluations conducted on V-- 5wt% Ti--20wt% Nb andV--5wt% Ti--20wt% Nb-0.05 wt% O at 2000 deg F in helium showed that the addition of 0.05 wt% oxygen resulted in approximately a 40% increase in strength. A large number of vanadium-base alloys were also evaluated for tensile strength at 2400 deg F. The highest 2400 deg F ultimate tensile strength measured was 12,700 psi for the alloy Y--1 wt% Ti--60 wt% Nb, a value comparable to that measured for several commercial and experimental niobium-base alloys. In addition, several compositions were equally as strong on a density- corrected basis. (auth)
