Description
Summary:•A modified Hoch–Arpshofen model with temperature-dependent parameters is proposed.•The enthalpies of formation of multicomponent liquid alloys have been calculated using the modified model.•It improves accuracy of the Hoch–Arpshofen model and can be used to calculate thermodynamic properties of multicomponent liquid alloy systems. A modified model with temperature-dependent parameters is proposed based on the Hoch–Arpshofen model. The enthalpies of formation of multicomponent liquid alloy systems were calculated using the modified model. Results for the Pb-Sn-Zn, Cd-Ga-Sn, Bi-Cd-Ga-Zn, Bi-Cd-Ga-In-Zn, Cd-Ga-In-Sn-Zn and Bi-Cd-Ga-In-Sn-Zn systems are in excellent agreement with experimental data and highly accurate than obtained via the original Hoch–Arpshofen model, which indicate that the method is reliable.
