DEVELOPMENT OF A Ti-Al-Cb ALLOY FOR USE AT 1200 - 1800 F

Abstract

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.
