논문 초록 (Abstract)
TiAl alloys have received a lot of attention due to their high specific strength, wide applicability and their potential to replace Ni based superalloys. However, the TiAl alloys exhibits low creep properties at ∼800 °C and brittleness at room temperature. In the present study, phase equilibria of the Ti–Al–Mo system were calculated via PandatTM software. A few alloy compositions were selected for experimental study and the corresponding microstructures were investigated. The two-phase or three-phase microstructures were composed of α, β and γ which can be obtained through proper adjustment of the alloy composition in the Ti–Al–Mo system. The phase selection and control are discussed in terms of isothermal phase diagram.
