Powder metallurgy (PM) TiAl-based alloy can solve the problems associated with ingot metallurgy, such as composition segregation, coarse microstructure and shrinkage cavity. In this paper, recent progress of PM TiAl-based in termetallics in powders preparation, sintering, forming and heat treatment was reviewed. Some methods were introduced including cold crucible vacuum induction melting gas atomization (VIGA–CC), electrode induction melting gas atomization (EIGA), hot isostatic pressing (HIP). Furthermore, the research direction of PM TiAl-based intermetallics was pointed out.
