VANADIUM ALLOY STUDIES.
Abstract
Alloys based on V-20Cb and V-Cb-Ta, enriched in Ti, Si, and C were fabricated by arc-melting, hammer forging, and cold rolling to sheet or foil; the silicon and carbon additives promoted age hardening. The V-20Cb-10Ti base alloys were highly fabricable and had density-corrected strengths up to 1,300,000-in. at -320F, 800,000-in. at 1200F, and 250,000-in. at 1800F. Somewhat reduced fabricability was noted for V-Cb-Ta base alloys which contained from 28 to 54% V. The tantalum-containing materials were nearly as strong as the V-Cb-Ti alloys up to 1200F, and they were much stronger in the 1800 to 2400F range. Density-corrected strengths were above 400,000-in. at 1800F, and 160,000-in. at 2200F. Improved workability but slightly reduced strengths (Density-corrected) were noted in V-Cb-Ta alloys as vanadium contents were raised. (Author)
