摘    要：介绍了高温钛合金的发展与现状，着重分析了美国、英国、俄罗斯高温钛合金的发展和现状，探讨了高温钛合金的发展方向，并针对高温钛合金研究和设计中存在的困难，初步提出了一些解决问题的途径，即寻找新的添加元素、发掘与应用稀土元素、开发以Ti₃Al和TiAl化合物为基的抗蠕变合金、研究抗氧化涂层等。

Abstract: The history and current situation of the high-temperature Ti-based alloys were reviewed, with the emphases on the cases of the United States, Great Britain and Russia. The development trends of those alloys were discussed . In the light of the difficulties met in the development and design of those alloys, several ways have been proposed to solve those problems, i.e. selecting new alloying elements, using additives of rare earth elements, designing Ti₃A- and TiAl-based creep resistant alloys and developing oxidation-resistant coatings.
