IMPROVED VANADIUM-BASE ALLOYS. Bimonthly Report No. 2
Solid solution and dispersion-strengthened vanadium -niobium base alloys were fabricated to sheet by hot or cold rolling. Excellent workability of V--60 wt.% Nb base materials was demonstrated by cold rolling directly to 0.050inch sheet. Tensile data at 2000 deg F show that maximum strengthening of the V--20 wt.% Nb and V--60 wt.% Nb bases were produced by 5 wt.% and 0.5 wt.% titanium, respectively. Room-temperature properties of welded vanadium -niobium base alloys were similar to those of the parent materials: welded V--5 wt.% Ti--20 wt.% Nb passed a 1.2t bend, and V--60 wt.% Nb passed a 2.5t 180 degree bend. At 2000 deg F, the welded specimens approached the strength of the base metals, but were less ductile. (auth)
