An Analytical Investigation for Thermodynamic Properties of the Fe–Cr–Ni–Mg–O System

Abstract—Present study performs excess energy values, activity coefficients and partial free energy associ ated with the penternary Fe–Cr–Ni–Mg–O, quaternary Au–In–Sn–Zn and ternary Pb–Au–Bi liquid alloys, based on published binary thermodynamic descriptions and Chou’s model for extension into higher order systems. Using Kohler, Muggianu and Chou’s model the obtained results in the present study were compared to available experimental data.
