PILOT EVALUATION OF VANADIUM ALLOYS. Bimonthly Report No. 6, July 18, 1962-September 17, 1962
A1loys of Nb--V containing reactive and refractory metal and interstitial additions were prepared as 200-gram nonconsumable-electrode arc- melted ingots. At the 20 wt.% Nb level, strengths as high as 54,000 psi at 2000 deg F were measured for a V--5 wt.% Ti--20 wt.% Nb--10 wt.% Ta composition; at 60 wt.% Nb, the strongest alloy was V-1 wt.% Ti--60 wt.% Nb--2.5wt.% Mo--0.5 wt.% Ru which had an ultimate tensile strength of 65,000 psi at 2000 deg F. Additions of W, Ta, or Mo generally caused reduced fabricability and ductility. Extruded bar stock and warmrolled plate and sheet from the 100-pound consumableelectrode arc- melted ingot of V--1 wt.% Ti--60 wt.% Nb were received at the Foundation. Initial examination indicated that this material was free from defects. (auth)
