A modified Hoch–Arpshofen model for the calculation of enthalpies of formation of multicomponent liquid alloys

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.
