IMPROVED VANADIUM-BASE ALLOYS. Bimonthly Report No. 3 for April 1, 1961- May 31, 1961
Promising V-Nb ailoys were produced and fabricated to sheet by hot or cold working techniques. Excellent workability was evidenced by the fact that most of the compositions could be rolled to 0.050-inch sheet. Metallographic and hardness studies on the sheet materials indicated that boron and carbon added to V-1Ti-60Nb raises the recrystailization temperature 200 deg to 400 deg F. Short- time stressrupture properties were determined for several alloys at 2000 deg F; the alloy V-5Ti-20Nb-0.05C failed after 22 hours at a stress of 10,000 psi. A 50- pound ingot of V-5Ti-2ONb was double arc-melted and extruded to 3-inch diameter bar by a commercial vendor. Externally the bar appeared to be sound. (auth)
