Popis:	The Fe–Zn binary system has been evaluated using the calculation of phase diagram (CALPHAD) method. In the evaluation, the ζ (FeZn13) phase is treated as a stoichiometric compound because of its rather narrow solution range, and the δ (FeZn10), the Γ1 (Fe5Zn21) and the Γ (Fe3Zn10) phases are described using sublattice models because they all have a relatively wide homogeneity range. A consistent set of optimized thermodynamic parameters describing the individual phases of this system has been derived, leading to a better fit between the calculated results and the experimental data reported in the literature. The reproduction of the thermochemical and phase diagram information is reported in a series of figures and tables.
