COLUMBIUM ALLOY SHEET ROLLING PROGRAM.
Abstract
Six inch diameter, 300 lb. ingots of FS-85 (Cb-27Ta-10W1Zr) and B-66 (Cb-5V-5Mo-1Zr) were processed to produce 0.060 in x 18 in wide sheet. The FS-85 was successfully converted to target dimensions while the B-66 sheets did not meet the 18 in width criteria. The finished sheet was evaluated with respect to chemical and mechanical properties and weldability. The ingot to sheet yield for FS-85 was 51.1% while the yield for B-66 was only 21.5%. FS-85 was considerably easier to fabricate accounting for the greatly superior yield of finished sheet from ingot. The quality of the sheet produced was roughly equivalent for the two alloys except that the FS-85 had better flatness.
