摘　　要：The microstructures and mechanical properties of Cr13 super martensitic stainless steel after different heat treatments were studied. The results show that the structures of the steel after quenching are of lath martensite mixed with a small amount of retained austenite. With the raising quenching temperature, the original austenite grain size increases and the lath martensite gradually becomes thicker. The structures of the tempered steel are mixtures of tempered martensite and reversed austenite dispersed in the martensite matrix. The amount of reversed austenite is from 7.54% to 22.49%. After different heat treatments, the tensile strength, the elongation and the HRC hardness of the steel are in the range of 813-1 070 MPa, 10.1%-21.2% and 21.33-32.37, respectively. The steel displays the best comprehensive mechanical properties after the sample is quenched at 1 050 ℃ followed by tempering at 650 ℃. 关键词：马氏体不锈钢微观结构机械性能热处理回火马氏体奥氏体晶粒尺寸马氏体淬火板条马氏体
