Abstract: Owing to the limitation of the normal thermomechanical treatment on TiAl based alloy, a double-temperature heat treatment technology for hot forged TiAl based alloy was suggested. The effect of the new technology on microstructure and tensile properties of the alloy at ambient temperature was also studied. By TEM analysis, the mechanism that the double-temperature heat treatment improves the homogeneity of the microstructure in TiAl based alloy was discussed.
