PILOT EVALUATION OF VANADIUM ALLOYS. Bimonthly Report No. 4, March 18, 1962-May 17, 1962
Some twenty high-vanadium and V-60 wt% Nb base alloys containing refractory metal and interstitial additions were fabricated by hot and cold rolling techniques. All compositions were rendered to 0.050 inch sheet except those containing molybdenum or more than 0.l3 wt% combined oxygen and nitrogen. Tensile results at 2400 deg F showed that V-20 wi% Nb base materials had ultimate tensile strength values in the 8,000 to 10,000 psi range, whereas V-60 wt% Nb base alloys had strengths of 12,000 to l9,000 psi. Additions of 0.05 wt% oxygen or 0.03 wt% each of oxygen and nitrogen produced large strength increases in the V-60 wt% Nb base. A 100-pound ingot of V-1Ti-60 Nb was melted for extrusion and subsequent fabrication into bar, plate, and sheet for more detailed property evaluations. (auth)
