Abstract：With the development of China’s industrial technology, engine materials have become a barrier to the development of aviation technology. TiAl alloy has the advantages of low density, good oxidation resistance and high specific strength, and it is a promising alternative material for low-pressure turbine blades. In order to explore the application prospects of TiAl alloy prepared by laser additive manufacturing technology in aero-engines, this paper introduces in detail the TiAl powder required for laser additive manufacturing and related laser additive manufacturing technology, as well as the current research status. The advantages and drawbacks of using laser additive manufacturing technology for TiAl alloy are analyzed, and the problems that still need to be studied are proposed.
