摘　　要：分析低碳贝氏体钢主要有细晶强化、沉淀析出强化、组织强化、位错强化等强化机理。各强化机理互相影响、作用,其良好性能是各强化机理的共同作用,不可单一分割。The strengthening mechanisms, such as the fine grain strengthening, precipitation strengthen- ing and structure strengthening, dislocation strengthening for the low carbon bainitic steel were analysed briefly. Each strengthening mechanism interacts with each other, and its good performance is the result of the interac- tion of various strengthening mechanisms which cannot be divided.

关 键 词：高强度低碳贝氏体钢 细晶 沉淀析出 组织 位错
