对低碳钢进行冷轧变形,研究退火温度与退火时间对不同冷轧变形量低碳钢微观组织和力学性能的影响。结果表明,随着冷轧变形量的增加,低碳钢的屈服强度和抗拉强度升高,伸长率降低。在相同退火制度下,随着变形量的增加,低碳钢的伸长率先增加后降低。 The cold rolling deformation of low carbon steel was carried out to study the effect of annealing temperature and annealing time on the microstructure and mechanical properties of low carbon steel with different cold rolling deformation. The results show that with the increase of cold rolling deformation, the yield strength and tensile strength of mild steel increase, and the elongation decreases. In the same annealing system, with the increase of deformation, the elongation of low carbon steel first increases and then decreases.
