摘要
通过热模拟实验,研究了一种低碳钢显微组织的变化规律。在此基础上,进行两阶段多道次轧制和在适度冷却速度下控冷的热加工实验,分析了工艺参数对钢的显微组织的影响。结果表明,化学成分、应变量和冷却速度对低碳钢的显微组织有强烈的影响。通过优化工艺,获得了以等轴状铁素体为主的铁素体和珠光体组织,从而提高材料的力学性能。
The microstructure evolution of low carbon steel was investigated by the thermal simulation test.Based on this,through two-staged multi-pass rolling and hot rolling experiments under moderate cooling rate,analyzing the effects of process parameters on the microstructure.The results show that microstructure of low carbon steel is strongly affected by technical parameters of thermo-mechanical control process（TMCP） such as chemical composition,the strain and the cooling rate.The microstructure of polygonal ferrite and pearlite is obtained to enhance mechanical properties by the optimal TMCP.
