Experimental investigation of phase equilibria in the Cu–Ni–Zr system

摘要: 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 (Cu 20–40 Ni 40–60 Zr 20) and T2 (Cu 20–25 Ni 60–65 Zr …
