| 摘 要： | 利用光学显微镜、扫描和透射电镜观察和分析了不同钒、氮含量非调质钢经奥氏体热变形后以不同速度冷却到室温的显微组织.结果表明,随氮含量增加或钒含量减少,珠光体增多;钢中有大量的不仅在先共析铁素体且在珠光体铁素体中析出的小于3 nm的纳米级析出相;冷速增加,铁素体变细且数量减少,继而出现贝氏体、马氏体,同时钒、钛的析出相尺寸变小,成分由以(Ti,V)N为主,转以(Ti,V)C为主. |

| Abstract: | The microstructures of non-quenched and tempered steel with different vanadium and nitrogen contents, cooled to room temperature at different cooling rates after being deformed in austenite,were observed and analyzed using optical microscope,scanning and transmission electron microscope.The results indicate the amount of pearlite increases as nitrogen increases or vanadium decreases.A large amount of nano-precipitates with size less than 3 nm were found in both pre-eutectoid and eutectoid ferrite.With cooli... |
| Keywords: | non-quenched and tempered steel with vanadium and nitrogen microstmcture precipitates |
