| Abstract: | Many of the problems associated with ingot metallurgy (IM), such as macrogregation, dendritic segregation, chemical inhomogeneity, and regions of varying microstructure can be solved by powder metallurgy, which is an important method to fabricate TiAl alloy. The research states of TiAl alloy in powder metallurgy at home and abroad were reviewed and the fabricatrion processes of TiAl powder were discussed, including prealloyed method, element powder method, mechanical alloying, and their sintering techniques. Their respective advantages and disadvantages, mechanical properties, and some improvement of TiAl powder metallurgy fabrication in future were finally pointed out. |
