摘要 通过热轧实验研究了控轧控冷工艺和化学成分对两种含Nb微合金化钢厚度方向显微组织的影响。结果表明,从试样芯部到1/4厚度位置,再到表面层,铁素体晶粒和贝氏体束尺寸越来越小,相应位置处的铁素体量逐步增多,而M-A量则经历了先增加后减少的过程,并在1/4厚度位置处达到了峰值。在控轧控冷工艺参数相近的情况下,在厚度方向同一位置处,Nb-Ti钢的铁素体晶粒、贝氏体束以及M-A组元尺寸更小,并且厚度方向不同位置处的组织差异较Nb钢小,对减小厚度效应更为有利。 Effects of thermomechanical controlled processing and chemical composition on the microstructure through thickness direction of Nb steel and Nb-Ti steel were investigated by hot rolling experiment.The results showed that ferrite grain and bainite packet were smaller and smaller,and ferrite amount was increased gradually from central region through a quarter of the thickness to surface layer of the specimen.Whereas M-A amount was increased firstly,then decreased and reached peak value in a quarter of the total thickness.Under the condition of similar TMCP parameters,ferrite grain,bainite packet and M-A constituent sizes were smaller of Nb-Ti steel at the same region through thickness direction,and microstructure difference in different regions of thickness direction was smaller than that of Nb steel,which was more favorable to reduce thickness effect.
