本文讨论了燃气涡轮发动机、飞机骨架和其它领域用的高温钛合金的发展。钛的高比强使其成为大功率高推重比发动机的、非常有吸引力的设计选材对象。合金的化学效应和显微组织在确定机械性能方面的作用是值得考虑的两个问题。合金的改型和涂层研究的发展将导致钛在高温领域的用量增加。 This article discusses the development of high temperature titanium alloys for gas turbine engines, aircraft frames, and other fields. The high titanium ratio makes it a very attractive design choice for high-power, high-thrust-to-weight engines. The chemical effects of the alloy and the role of microstructure in determining mechanical properties are two issues worth considering. The development of alloy modification and coating research will lead to an increase in the amount of titanium used in the field of high temperature.
