Ti-6Al-2Sn-4Zr-2Mo is near α titanium alloy with high creeping resistance, which is working at
470℃-550℃ and mainly used for manufacture of discs and blades of high pressure compressor of aero-engine. This alloy was successfully developed in 1974 by foreign and was done a lot of basic and applied research and development. At present, Ti-6242 alloy has been successfully used for aero-engine of F414, F119 and TRENT800 aircrafts.
