<p>The phase equilibria of the Zn-Cu-Cr ternary system at 450 and 600&#xa0;°C were studied using equilibrium alloy method. The phase constitution of the alloys were analyzed by means of the scanning electron microscope equipped with energy dispersive x-ray spectroscopy (SEM-EDS), and x-ray diffraction (XRD). The results show that five three-phase regions exist in the isothermal section at 450&#xa0;°C, and four three-phase regions exist in the isothermal section at 600&#xa0;°C. No new ternary compound was found in the system. The (Cr) phase is found in equilibrium with all phases. At 450&#xa0;°C the solubility of Cu in CrZn₁₇ is 0.69 at.%, and the maximum solubility of Cr in CuZn₄ (ε), Cu₅Zn₈ (γ), and CuZn (β′) is 1.15, 0.6, and 0.43 at.%, respectively. At 600&#xa0;°C the maximum solubility of Cr in CuZn₃ (δ), Cu₅Zn₈ (γ), and CuZn (β) is up to 1.95, 1.03, and 7.8 at.%, respectively.</p>
