The microstructure of Ti-33wt-% Al-(1.6-4.5)wt-% Mn alloys are composed of γ+α_2 phases,but the volume of x_2-phase is a little.Mn alloying decreases the lattice parameters a and c of γ-phase and the c/a ratio becomes nearly to one,because the atomic radius of Mn is less than the atomic radius of Ti or Al.Mn alloying promotes the formation of twins in γ-phase and increases the ability of plastic deformation of TiAl alloys at room tem- perature.
