A study was made on the Ti--Al-Nb system for high temperature alloys with useful strengths above 1200 deg F. Composition variations included: niobium from 17.5 to 35%, aluminum from 12.5 to 17.5%, and the addition of smaller amounts of zirconium, hafnium, tin, carbon, or boron. Short-time tensile properties were determined for one strain rate (0.0029 in./in./min.) at 1600 deg F. Stressrupture properties were obtained for a variety of temperatures and stresses. The Larson-Miller parameter was used to present these stress-rupture data so that the rupture life at various temperatures could be presented on a single plot for each alloy. (auth
