DISPERSION-STRENGTHENED VANADIUM ALLOYS.
Abstract
Vanadium-niobium base alloys containing additions of titanium, zirconium, or hafnium in combination with up to 0.2wt.-% carbon were prepared by arcmelting and fabricated to sheet for elevated temperature creep tests. Compositions based on V-60Nb and containing titaniun or zirconium with carbon had good fabricability, but V-60Nb1Hf-C and V-40Cb-30Ta-C alloys were difficult to work. Creep tests conducted on siliconized specimens in 2000 F air showed that large carbon additions (0.1 and 0.2wt.-%) produced increased creep rates in V-60Nb base alloys. The most creep resistant composition was V-60Nb-10Ta-1Zr0.075C which exhibited 1.25% creep in 2.5 hours under a stress of 11, 200 psi. (Author)
