Abstract: β titanium alloy is widely used in the fields of high performance and advanced engineering such as aerospace, marine, military and biomedical, but the current process application puts forward higher requirements for its properties. β titanium alloy can be strengthened by heat treatment. The heat treatment process of β titanium alloy in recent years was reviewed. Firstly, the main phase composition and phase transformation of β titanium alloy were systematically overviewed. Then, the effects of typical heat treatment process, plastic deformation mechanism and newly developed pre-deformation aging process on microstructure evolution and properties were described and analyzed. Finally, the development trend of heat treatment process of β titanium alloy was prospected.

Key words: β titanium alloy, heat treatment, precipitated phase, pre-deformation aging process
