_{:TiAl alloy are high-profile advanced structural material because of its high strength-to-weight ratio and high service temperature, which has great potential in aerospace,automotiveandotherfields. However, TiAl alloy has poor thermal workability and is difficult to be formed by traditional methods. Powder metallurgy has a significant advantage in preparing complex TiAl alloy parts due to the characteristics of near-net forming.In recent years, researchers have done a lot of work on sintering technology of TiAl alloy powder and made some progress.The Process, microstructure,mechanical propertiesandparts of TiAl alloy using spark plasma sintering (SPS), hot isostatic pressing(HIP), hot pressing sintering,spray depositionand injection moldingin recent years were reviewed. The features and existing problems of above preparation methods were discussed. Meanwhile, some suggestions on powder metallurgy forming TiAl alloy parts and its future development were proposed.}
