Abstract：The effect of granular bainite, ferritepearlite on the strength, ductility and toughness of lowcarbon steel was investigated. The results indicate that the strength and toughness of lowcarbon granular bainite steel are higher than that of ferritepearlite steel. And for granular bainite steel, not only grain refinement and dislocation strengthening, but also dispersion strengthening are effective.
