Abstract

The isothermal Cu–Ti–Zr phase diagram at 800°C was constructed by means of 36 equilibrated alloys. Electron microprobe analyses were used to determine the phase compositions and phase relationships. Most of the Cu–Zr binary intermetallic phases show a large Ti solubility and extend to the ternary region. CuTi₂ and CuZr₂ form a complete solid solution as a Cu(Ti,Zr)₂ phase. One ternary phase, Cu₂TiZr, formed at the central region. These phase relationships are quite different from the 703°C isotherm mainly determined by X-ray analysis.
