| Abstract: | The microstructure evolutions of AI-Si-bearing low carbon steel during multi-pass hot deformation and subsequent continuous cooling process were studied. The results show that ferrite/bainite dual phase microstruture is obtained by controlling multi-pass rolling and cooling process. The ferrite/bainite dual phase steel has low yield strength, high tensile strength, low yielding ratio and continuous yielding behavior. |

| Keywords: | ferrite bainite dual phase steel microstructure mechanical property |
