主 题：transition metal non-transition metal intermetallic compound formation criterion.
摘 要：A four-parameter model based on the extended Miedema’s cellular model of alloy phases and pattern recognition methods has been used to study the regularities of the formation of binary intermetallic compounds between tran-sition element and non-transition element. The formation criterion can be expressed as some inequities of electronega-tivity , the valence electron density in Wagner-Seitz cell nws1/3, Pauling’s metallic radius R and the number of valence electrons in atom Z or their functions. According to these empirical criterions, the unknown binary alloy system can be predicted, the predicted result is better than that of Miedema’s two-parameter model.
