The isothermal section of the Cu–Ti–Zr system at 1023 K measured with diffusion-triple approach

The isothermal section of the Cu–Ti–Zr ternary system at 1023 K has been constructed by using diffusion triple together with electron probe microanalysis, which consists of 15 single-phase fields, 25 two-phase fields and 13 three-phase fields. A ternary phase, Cu2TiZr, is confirmed. Most of the Cu–Ti and Cu–Zr binary phases show large ternary solubility, in which Zr and Ti can substitute for each other to a certain degree. In addition, at 1023 K, the CuTi2 and CuZr2 phase can form a continuous solution phase in the Cu–Ti–Zr ternary system.
