【Abstract】 An overview of studies on M5Si3-type silicides since 1950’s is presented. Major issues of physical metallurgy involved in the study of M5Si3-type silicides, such as phase diagrams and thermodynamics, crystal structures of the compounds and their stability chemical and physical properties of the compounds as well as their manufacture, alloying and toughening effects are discussed. The trend of the studies and the applications of M5Si3-type silicides are also expected.更多还原
