Notes:
TiAl alloys are powerful candidates for light weight high temperature structural materialsbecause of their excellent high temperature strength, low density and good oxidation resistance.Unfortunately, TiAl alloys are difficult to machine and hot working due to ordered structure, whichimpede large-scale application. Synthesis and superplastic deep drawing of a TiAl alloy were studied.Mechanically synthesized fine crystalline Ti/Al composite powders as precursor of TiAl alloy. TheTiAl alloy with fine grain via reactive sintering was obtained. The deformation behavior under biaxialstress by means of deep drawing was achieved. The optimum temperature is 1100°C≤T≤1150°C. Themicrostructures corresponding to deep drawing in the part were studied
