摘要：

A new set of formulae for calculating activities and activity coefficients of components at a fixed temperature in a binary system are presented from the phase diagram involving the equilibria between liquid and solid solutions based on the knowledge of entropies of fusion of components and those of liquidus and solidus compositions. The application of this new method to Cd-Mg system shows that this new method is feasible. It is expected that these formulae will find its applications in alloys, melts and slag, especially when experimental data are not available. © 1990.
