Abstract

The phase relationships of the Cu-Ti-Er ternary phase diagram at 773 K (500 °C) were investigated mainly by means of X-ray powder diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), and differential thermal analysis (DTA). It is confirmed in this work that the binary compounds Cu9Er2 and Cu7Er2 exist in the Cu-Er binary system at 773 K (500 °C). The stability of the CuTi3 phase is confirmed in the Cu-Ti system. After heat treatment at 1023 K (750 °C) for 90 hours, the phase CuTi3 is observed in the microstructure of the alloy 25Cu75Ti. The temperature of the eutectoid transformation, namely, β-Ti ↔ α-Ti + CuTi3, is determined to be 1078 K (805 °C) in this work. The 773 K (500 °C) isothermal section consists of 14 single-phase regions, 25 two-phase regions, and 12 three-phase regions. None of the phases in this system reveals a remarkable homogeneity range at 773 K (500 °C).
