摘　　要：通过金相显微镜、扫描电镜以及力学检测等方法，研究了正火工艺对12CrlMoVR的组织性能的影响。结果表明：随着正火时间的增加，钢板的屈服强度和抗拉强度均降低。正火后，8mm厚钢板组织为铁素体＋珠光体＋贝氏体，60mm厚钢板组织主要为铁素体＋珠光体。This paper studied the effects of normalizing process on microstructure and properties of 12Crl MoVR steel by means of optical microscope, scanning electronic microscope and mechanical tests. The results showed that the yield strength and tensile strength were reduced with the normalizing time increasing. The microstructure with the thickness of 8mm was F ＋ P ＋ B after normalizing, and the microstructure with the thickness of 60ram steel was F ＋ P.
