摘　　要：通过对20Cr13、30Cr13、40Cr13马氏体不锈钢进行不同温度下空冷,研究了加热温度和碳含量对马氏体不锈钢显微组织和硬度的影响。结果表明:随加热温度升高,马氏体板条开始粗大,出现了枝状晶界,并且硬度增加;随碳含量增加,马氏体和碳化物增加,马氏体板条逐渐向片状过渡,并且硬度增加。20Cr13, 30Cr13 and 40Cr13 martensitic stainless steel were heated at different temperatures and then air-cooled, and effects of heat temperature and carbon content on mierostructure and hardness were investigated. The resuhs show that the martensite laths become coarse, trigeminal grain boundary appears and the hardness increases along with the increase of heating temperature. With the increase of carbon content, martensite and carbide increase, the lath martensite gradually transforms to plate martensite, and the hardness increases.
