The creep behavior of Ti alloys is complicated and can usually be divided into low temperature creep, grain boundary slip creep, diffusion creep and dislocation creep, so on. Some important factors, such as temperature, time and microstructure, influence the creep property of Ti alloys due to the different creep types. This paper reviews the effects of creep parameters, microstructure, and Si element on the dislocation creep behavior of Ti alloys, and the possible mechanism of improving the creep resistant of alloys are also discussed.
