The interface temperatures of primary phase β and peritectic phase α were calculated for different growth conditions. According to the criterion of the maximum growth temperature, the phase selection and microstructure evolution of Ti-(44-50)Al were theoretically studied and a microstructure-selection map of TiAl stable state solidification as a function of the melt composition and the G/v ratio was constructed.
