Abstract
Phase equilibria in the Cu–Ni–Zr ternary system have been measured through alloy sampling combined with diffusion couple approach. According to the phase relations identified with electron probe microanalysis and X-ray diffraction techniques, isothermal sections at both 1073 and 1293 K were constructed. It is evident that remarkable ternary solubility occurs in almost all binary intermetallic phases at both temperatures. The formerly reported ternary compounds T1 (Cu20–40Ni40–60Zr20) and T2 (Cu20–25Ni60–65Zr15) were not verified in this work. No other ternary compound was detected. In addition, continuous dissolution between Cu10Zr7 and Ni10Zr7 at 1073 K was observed.
