A general model for the calculation of crystal nucleation kinetics in general binary melts was developed. The model calculates the free energy change of nucleation by maximizing it relative to the composition of the nuclei. It was used to calculate crystal nucleation temperatures in binary systems and results were shown to agree well with maximum undercooling data obtained in dispersion experiments. If the solid and liquid solutions are regular solutions, the model reduces to the Thompson and Spaepen model with slight approximation. The model is expressed in differences between terms at arbitrary temperature and terms at the liquidus temperature. This simplifies the calculation significantly.
