Abstract The microstructures of Ti-33wt-%Al-(1.6--4.5) wt-%Mn alloys arecomposed of γ+α_2 phases, but the valume of α_2 phase is a little. Mn alloying de-creases the α and c lattice axes of γ phase and the c/α value is more nearly to one,because the atomic radius of Mn is less than the atomic radius of Ti or Al. Mnalloying promotes the formation of twins in γ phase and increases the ability ofplastic deformation of TiAl alloys at room temperature.

Key words: TiAl alloys microstructure and property Twin
