Abstract Ti-48Al-2Nb-2Cr alloy was repaired by laser wire feeding technology. The surface forming and microstructure evolution of TiAl alloy repaired by laser wire feeding were analyzed. The results show that except for a small amount of micro-cracks in the heat affected zone near the root of the repair layer, the central area of the repair layer is well formed. The center of the repair layer is mainly acicular α′ martensite, and the average grain size is about 26 μm, which is smaller than the average size of the base metal Ti-48Al-2Nb-2Cr alloy of 50 μm. The bonding zone is composed of α phase and γ phase, and the average grain size is 42 μm. The average hardness of the central area of the repair layer is 510HV, which is much higher than the base metal with hardness of 325HV.

Key words： laser wire feeding repair repair layer forming structure transformation micro hardness
