In order to develop feasible hot processing technologies, hot workability of TiAl alloys need to be improved. The hot deformabili ty of tested alloys, Ti-46.5Al-2.5V-1.0Cr and Ti-46.3Al-2.5V-1.0Cr-(0.3～0.5)Ni-(0.01)Mg (mo le fraction, %), was evaluated by hot compression tests over the temperature ran ge from 950 to 1050 ℃ and strain rate range from 0.01 to 1.0 s-1. It was found that the hot deform ability of TiAl alloys was obviously improved by minor additions of Ni and Mg.
