Abstract:The researches and prospects of titanium alloys for aircraft were reviewed. Titanium alloys can be divided into α titanium alloy, α+β and β titanium alloy from the perspective of alloy matrix phase composition. The recent development and application of titanium alloys in the aircraft engine, aircraft and aerospace fasteners were introduced. The problems of titanium alloys applied to the aerospace industry were also discussed. It shows that improving the thermal stability under high temperature, strengthening the creep resistance and lowering the cost reduction are the future development directions of titanium alloys for aircraft.
Key words: titanium alloy; aerospace application; aircraft engine; airframe alloy; aerospace fastener
