Abstract: Selective laser melting and electron beam selective melting additive manufacturing are ideal advanced high energy beam additive manufacturing techniques. The selective laser melted and energy beam selective melted Ti-Al alloy had a fine microstructure, and better mechanical properties than the cast alloy. The alloy can obtain good high-temperature creep resistance and ductility by reasonable heat treatments after the forming. The high energy beam additive manufacturing technique can solve the traditional forming problem of Ti-Al alloy component. The research progress on the preparation of Ti-Al prealloyed powder, the process and application of selective laser melting and electron beam selective melting, and the microstructure and properties of Ti-Al alloy are reviewed. The future research direction of Ti-Al alloy prepared by high-energy beam additive manufacturing is prospected.
