Abstract: A non-burning Ti-V-Cr alloy which is heat treated to decrease its susceptibility to embrittlement in gas turbine engine compressor applications. The invention heat treat cycle consists of an isothermal holding period below the alpha solvus temperature, a slow ramp down to a lower temperature, a second holding period at a lower temperature, a third ramp down to an even lower temperature, and a final holding period at the third temperature. Other suitable heat treat cycles within the concept of the invention include a single holding period below the alpha solvus temperature double holding periods below the alpha solvus temperature with a ramp from a higher to a lower temperature and a continuous ramp below the alpha solvus temperature with no holding period.

Abstract translation: 一种不燃烧的Ti-V-Cr合金，经过热处理以降低其在燃气轮机发动机压缩机应用中的脆化敏感性。 本发明的热处理循环由低于α溶解温度的恒温保持期，缓慢下降到较低温度，较低温度下的第二保持期，降至更低温度的第三斜坡，以及最终保持期 在第三个温度。 在本发明的概念内的其它合适的热处理循环包括低于αsolvus温度的双重保持期低于α溶解温度的单个保持期，具有从较高温度至较低温度的斜坡，以及低于αsolvus温度的连续斜坡， 持有期
