Thermodynamic assessment of Zn-Fe-Nb ternary system

摘要：

　　The Nb-Zn system has been thermodynamically investigated within the CALPHAD approach by combining available experimental data and the data from ab initio calculations of the formation enthalpies for NbZn2, NbZn3 and NbZn15.The isothermal sections at 723 K and 873 K of Zn-Fe-Nb ternary system were thermodynamically optimized where one stoichiometric ternary phase (τ) and the ternary solubility in intermetallic compound (ε) were taken into consideration.The calculated diagrams are in reasonable agreement with the experimental and thermodynamic data.Furthermore, liquidus projection was predicted accordingly.
