Prediction of the thermodynamic properties of quaternary liquid alloys by modified coordination equation

The coordination numbers in the molecular interaction volume model (MIVM) can be calculated from common physical quantities of pure metals. A significant advantage of the model lies in its ability to predict thermodynamic properties of quaternary liquid alloys using only binary infinite dilute activity coefficients, and the predicted values are in good agreement with the experimental data of quaternary liquid alloys, which show that the model is reliable, convenient and economic.
