A study was made on Ti-Al-Cb system for high temperature alloys with useful strengths above 1200 F. During the present program composition variations included columbium 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 F. Stress-rupture 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.
