高温钛合金的现状与前景

High Temperature Titanium Alloys: Status and Perspective

简要回顾国内外固溶强化型高温钛合金材料的发展历史,分析英、美、俄等国的高温钛合金研究与应用情况及发展趋势.介绍国内自主研制、使用温度在550～ 650℃范围内的三种钛合金新材料及其相关技术发展,对国内高温钛合金材料进行初步梳理.参考国外高温钛合金研究、应用经验及发展趋势,结合国内实际情况,对国内高温钛合金材料体系的建立及完善提出具体建议,并展望国内高温钛合金近期研究重点和未来发展方向.

The history of solid solution strengthened high temperature titanium alloys was briefly reviewed and those alloys developed in the UK,USA and Russia were compared.Three kinds of alloys,Ti55,Ti60 and Ti65,covering the temperature range of 550-650℃,and related welding technology were introduced.Suggestions for perfecting the systematics of high temperature titanium alloys in China are made based on an overview of the status quo.Six key issues that should be tackled in the near future are identified and discussed.
