Improved Vanadium-Base Alloys

Title: Improved Vanadium-Base Alloys
Creator: Rajala, B. R.; Holtz, F. C.

Abstract: Promising V-Cb alloys 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-60Cb raises the recrystallization temperature 200 to 400 F. Short-time stress-rupture properties were determined for several alloys at 2000 F; the alloy V-5Ti-20Cb-0.05C failed after 22 hours at a stress of 10,000 psi. A 50-pound ingot of V-5Ti-20Cb was double arc-melted and extruded a 3-inch diameter bar by a commercial vendor. Externally the bar appeared to be sound.
