| 摘 要： | 利用Gleeble3500热模拟试验机,结合光学显微镜,研究V微合金化热轧双相钢在不同控轧控冷条件下的相变行为及组织演变规律.结果表明.变形温度为850℃、变形量为50%时,不同冷却速度和保温温度下的组织均由铁素体、贝氏体和马氏体组成.第二相的体积分数随冷却速度的增加而增加,随保温温度的升高而降低,冷却速度的变化比保温温度的变化对第二相体积分数的影响大.最佳冷却速度应控制在5～25℃/s. |

| Abstract: | Transformation and microstructure of V micro-alloyed dual phase steel under different process parameters were studied using Gleeble3500 thermal-mechanical simulation and optical microscope.The experimental results show that the microstructure with different cooling rates and holding temperature is all composed of ferrite,bainite and martensite when the deformation temperature is 850 ℃ and reduction of 50%.At the same holding temperature,the second-phase fraction increases with the increase of cooling rate.While at the same cooling rate,the second-phase fraction decreases with the increase of holding temperature.The influence of cooling rate is bigger than that of holding temperature.The best cooling rates should be controlled at 5 ～25 ℃/s. |
| Keywords: | dual phase steel micro-alloying transformation |
