Abstract：
Titanium alloy has the advantages of high specific strength,high hot strength,favorable corrosion resistance and high thermal strength,etc.,Which has become one of the main structure material of aircraft material.With the continuous progress of aeroengines,higher-working-temperature titanium alloys have been demanded.Recently,the highest temperature of mature using high temperature titanium alloy is 600℃.such as Ti1100(USA),IMI829(UK),IMI834(UK),BT18Y(Russia),BY36(Russia),etc.Then property features at 600℃for several typical high temperature titanium alloys were reviewed,and finally the key developing directions in the future are proposed.
