Thermodynamic assessment of the Pr–Zn binary system

On the basis of available experimental data of phase diagram and thermodynamic properties, the Pr–Zn binary system has been optimized using the CALPHAD approach. The phases, including liquid and bcc_A2(βPr) were treated as substitutional solutions, while the intermetallic compounds, including PrZn, PrZn2, PrZn3, Pr3Zn11, Pr13Zn58, Pr3Zn22, Pr2Zn17 and PrZn11 were modeled as stoichiometric compounds. As the result of optimization, a set of self-consistent thermodynamic parameters has been obtained, which can be used to reproduce the reported experimental data.
