Copper based amorphous alloy have a great attention in the recent years because of its high glass forming ability (GFA), lower cost, and good mechanical properties. Cu-Zr amorphous alloys are quite popular among the other amorphous alloys. Titanium (Ti) can be added to substitute some Zirconium (Zr) elements in Cu-Zr amorphous alloys to improve the mechanical properties as well as the glass forming ability.
In this study focused on the calculation of phase diagram (CALPHAD) to predict the metallic glass region. In order to re-assessed the thermodynamic parameter, the experimental investigation of phase equilibria in Cu-Ti-Zr ternary system should be understand well. The phase equilibria of the Cu-Ti-Zr have made by arc melting method and annealed at 703 oC for 1440 hours and then quenched in icy water. The isothermal section have composed of 15 single phases which include the ternary phase-Cu2TiZr, 17 two-phases regions, and 17 three-phases regions, respectively. The CuTi2-CuZr2 phases form continuous solid solution and the ternary phases located in the central portion of this isothermal section.
The re-assessment of Cu-Ti-Zr ternary phase diagram have established well. The thermodynamic parameters were used for predicting the metallic glass regions by combined the supressed intermetallic compounds (IMCs) phases, liquid miscibility gap, and spinodal curve. The predicted region have consistency with the experimental data and experimental result in bulk metallic glass alloys which done in this study.
