Ti-33wt-％Al-(1.6—4.5)wt-％Mn合金是一种γ+α_2两相合金,但α_2相的分数很少。由于Mn原子比Ti和Al原子半径都小,加入Mn使γ相晶格的α和c轴都减小,并使c/α更接近于1。Mn促进了γ相中孪晶的形成,并提高了TiAl基合金室温塑性变形的能力。
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.
