PROCESSING AND EVALUATION OF PRE-PRODUCTION QUANTITIES OF COLUMBIUM ALLOY SHEET.
Abstract
Single 300-lb, 6-in. ingots of FS-85 (Nb-27Ta10W-1Zr) and B-66 (Nb-5Mo-5V-1Zr) were converted to 0.050-by 18-in.-wide sheet and evaluated with respect to mechanical properties and weldability. FS-85 was judged to be the more fabricable alloy and this was attributed to its lower strength. The quality of the sheet produced was equivalent for the two alloys except that better flatness was achieved for FS-85. The tensile strength and stress-rupture behavior of B-66 was superior to that of FS-85 up to 2400F. Base metal bendability was less than 1T for both alloys. FS-85 had a 4T bend transition temperature of -250F as compared to -100F for B-66. The aswelded ductility of FS-85 was superior to that of B-66. (Author)
