摘要：

A modified cellular model is proposed for the investigation of melting point regularities of AB-type intermetallic compounds. By this model, five parameters of constituent elements: electronegativity difference, Delta X; valence electron density difference, Delta(Z/R(3)); electron-atom ratio, ela; metallic radius ratio, R(A)/R(B); and the average melting point of constituent elements, T-avg, are used to find a mathematical model for the melting point prediction, with the artificial neural network as the method of computation. The error of prediction is usually about 5% of the absolute temperature of melting point.
