提高燃气透平发动机部件用钛合金的最高使用温度是材料研究人员的目的。在这些应用中,其关键的机械性能是短期抗拉强度和在工作温度时的长期蠕变强度。美国俄亥俄州奈尔斯 RMI 钛公司报道,最近开发的二种压缩机使用的α-β钛合金,其最高使用温 It is the material researchers’ goal to increase the maximum temperature of titanium alloy for gas turbine engine components. In these applications, the key mechanical properties are short-term tensile strength and long-term creep strength at operating temperature. Niles, Ohio RMI Titanium Company reported that the two recently developed compressor used α-β titanium alloy, the highest temperature
