摘要：

Based on Miedema's semiempirical formation enthalpy model for binary alloys, free volume theory and a general solution model, a new model for prediction of activity interaction coefficient epsilon is proposed. The calculated results are better in agreement with the experimental values than the two previous models. The related theories and models are discussed according to the degree of agreement with experimental values.
