A thermodynamic model proposed for calculating the standard formation enthalpies of ternary alloy systems

Based on Miedema’s method for binary alloys, a thermodynamic model is proposed for calculating the standard formation enthalpies of ternary alloy systems. In the proposed model, both the atomic size difference of the constituent metals and the interaction between the third metal and the other two are taken into account. Compared with the Miedema’s original model, the newly proposed model can considerably improve the precision of calculation.
