Current Research Status and Development of High-temperature Titanium Alloys
In this paper,the development and present application of high-temperature titanium alloys were introduced.The research status and influence of alloying elements on high-temperature titanium alloys domestic and abroad were contrasted and analyzed.Titanium alloys with 600℃ of working temperature mainly include Ti1100 in USA,British IMI834,Russian BT18 and BT36,Chinese Ti60 and Ti600.Combined with the research focus on high-temperature titanium alloys,it was found that two key factors of creep resistance and oxidation resistance should be improved at higher than 600 ℃ of working temperature,for a stable and long-time operation of titanium alloys.The major research orientation for high-temperature titanium alloys in future was proposed to be preparation of particle-reinforced titanium-based composites and improvement of Ti-Al alloys using 3 D printing technologies.
