| 摘 要： | 对不同温度下变形和变形后再加热到奥氏体区的低碳钢SS400的显微组织进行了研究，结果表明：变形使奥氏体和铁素体晶界呈锯齿状，锯齿状的奥氏体晶界优先成为铁素体的形核位置，锯齿状的铁素体晶界有利于铁素体再结晶核心的形成。

| Abstract: | The microstructure of low carbon steel SS400 deformed at different temperatures and reheated to austenite region after deformation was studied. The results indicated that the grain boundaries of austenite and ferrite are sawteeth shape after deformation; the sawtooth austenite boundaries become preferential nucleation sites of ferrite, and the sawtoothed ferrite boundaries contribute to the formation of ferrite recrystallization nucleus. |

| Keywords: | deformation grain boundary austenite ferrite low carbon steel |
