Abstract

The phase equilibria of the Cu-Co-Zn ternary system at 800℃ and 1000℃ were investigated by electron probe microanalysis and X-ray diffraction. Results show that no ternary compound was found. At 800℃, the solubility of Co in the β-CuZn, and Cu in the β1-CoZn at 800℃ are 32.36 at% and 5.28 at%, respectively. The γ-Co₅Zn₂₁ and γ-Cu₅Zn₈ show that the same crystal structure, and thus an infinite region of mutual solubility is observed in the Cu-Co-Zn ternary system. It is confirmed that as the temperature rises from 800℃ to 1000℃, the liquid-phase region is further expanded. The isothermal section of 1000℃ is simple. The phases of β-CuZn, β1-CoZn, γ-Co₅Zn₂₁ and γ-Cu₅Zn₈ disappear. The region of liquid phase is very large.
