Abstract
A van der Waals model based on accurate free energies for solid and liquid hard‐sphere two‐component mixtures is described. The model is computationally simple, it readily describes the variety of solid–liquid phase diagrams observed in metallic, ionic, and molecular systems, and in addition it permits the study of phase diagrams as a function of pressure. Several well‐known empirical regularities in two‐component phase diagrams are found to be predicted by the model calculations. Quantitative comparison of theory and experiment for metallic mixtures shows good agreement.Keywords
