| 摘 要： | 研究了原始组织为马氏体、贝氏体和正火态组织的20SiMnTi钢经亚温淬火后强韧性。结果表明，具有马氏体和贝氏体组织的钢，经亚温淬火后的强韧性均优于正火态钢。钢的强化效应与两相的相对量和组织形态有关。

| Abstract: | The strengthening and toughening of 20SiMnTi steel whose original structure are martensite,upper bainite.low bainite and normalized structure respectively and then undergo subcritical quenching have been investigated.The examination results show that after subcrtical quenching the strengthening and toughening of steel with original structure of martensite or bainite is better than that of with normalized one.The effect of strengthening and toughening of steel have much to do with fraction and morphology of two phases |

| Keywords: | martensite bainite subcritical quenching strengthening and toughening |
