Effect of Heat Treatment on Microstructure and Properties of Cr15 Super Martensitic Stainless Steel

摘要：

　　The microstructure and mechanical properties of Cr15 super martensitic stainless steel after different heat treatment were studied by SEM and XRD.The results show that the microstructure of steel A and B are lath martensite and retained austenite after quenching.The original austenite grain size increases with the increasing quenching temperature.The microstructure is composed by tempered martensite and reversed austenite after tempering.The amount of reversed austenite in both steels increases first and then decreases with the increasing tempering temperature.Both of the tested steels have the best mechanical properties at 650℃ tempering temperature.
