Abstract:

Additional creep-stability tests and thorough chemical analyses were performed on Ti-8Al-1Mo-1V sheet mill annealed at 1350F 8 hr, rather conclusively showing that the substandard creep resistance at 1000F is associated with this lower annealing temperature. Evaluation of welded Ti-8Al-1Mo-1V was completed, which demonstrated that this alloy has good welded strengths and ductility, excellent creep properties, and good notch tensile characteristics at sub-zero temteratures. Additional crack propagation studies indicated that, at a lower annealed strength level 140 Ksi YS, the crack propagation resistance of Ti-8Al-1Mo-1V is markedly improved. The remainder of the five 1600-pound ingots of Ti-8Al-1Mo-1V were melted and a processing schedule was formulated. Slab samples from the first two heats of Ti-5Al-5Sn-5Zr and Ti-7Al-12Zr were examined macrographically and thoroughly analyzed chemically. Author
