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

Key words： granular bainite ferritepearlite impact toughness dispersion strengthening
