摘要
采用光学显微镜、扫描电镜、洛氏硬度计、冲击等试验方法,研究了碳含量对ZGCr17Ni2马氏体不锈钢组织和力学性能的影响。结果表明:碳含量从0.17%增加至0.99%时,ZGCr17Ni2不锈钢显微组织由珠光体+马氏体+残余奥氏体+碳化物+δ铁素体转变为珠光体+马氏体+残余奥氏体+碳化物+莱氏体,且碳含量增加,莱氏体含量增大;硬度由HRC35提高至HRC50,冲击功则由45 J降至8 J。
The effect of carbon content on the microstructure and properties of ZGCr17Ni2 martensitic stainless steel was investigated by means of optical microscopy, scanning electron microscopy, Rockwell hardness tester,and impact test method. The results show that, with the increase of carbon content in the range of 0.17%-0.99%, the microstructure translates from pearlite+martensite+retained austenite+carbide+delta ferrite to pearlite+martensite+retained austenite+carbide+ledeburite. The amount of ledeburite increases gradually with the increase of carbon content. The hardness is increased from HRC35 to HRC50, but the shock absorption energy is reduced from 45 J to 8 J.
