Abstract
The Cr-Zn binary system was critically assessed with the CALPHAD technique using the PARROT module of the Thermo-Calc software by taking into account new experimental measurements. The solution phases [liquid, body-centered cubic (bcc), close-packed hexagonal (cph)] were modeled with the Redlich-Kister equation. The intermetallic compounds CrZn13 and CrZn17 are treated as stoichiometric compounds. The experimental chromium solubilities at various temperatures modify the shape of the liquidus curve and are satisfactory for industrial applications. A set of parameters consistent with most of the available experimental data on both phase diagram and solubility measurements was obtained by optimization. A comparison with previous work is also presented.
