The Cu-Zr-Ti alloys are one of popular metallic glass systems due to their high glass-forming ability (GFA), lower cost, and good mechanical properties. The phase equilibria of the Cu-Zr-Ti ternary system are experimentally investigated first to reassess thermodynamic parameters. The isothermal section of the Cu-Zr-Ti ternary system at 703 °C is composed of 15 single phases including the ternary phase-Cu2TiZr, 17 two-phase regions, and 17 three-phase regions. The CuTi2–CuZr2 phases are formed as a continuous solid solution. The CuZr phase was not present in this ternary system. The calculation of phase diagram (CALPHAD) method can be used to predict the metallic-glass region. The suppressed intermetallic compounds, liquid miscibility gap, and spinodal curve were first combined to predict metallic-glass regions. The predicted region is in good agreement with the literature data and experimental results of the bulk-metallic-glass alloys applied in this study.
