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