摘　　要：铁素体晶粒超细化技术是大幅度提高低碳钢强度、韧性和节约资源的有效途径。分析现有研究结果,得出了最有效的铁素体晶粒细化技术,获得1μm左右的铁素体晶粒和σy≥750MPa,δ≥10%的力学性能,可对钢铁材料组织超细化技术的理论研究和实际应用提供参考。Ferrite grain uhrafining technology for low carbon steel could increase strength, toughness and save resource. Some recent research results were investigated and the most useful uhrafining technology of ferrite grain was obtained. The ferrite grain less than 1μm and mechanical propertiesσy≥750MPa,δ≥10% were also obtained. It will provide reference of theoretic research and engineering application for structure uhrafining treatment of iron and steel.
