冷轧带肋钢筋的应变时效引起钢筋强度升高,伸长率下降,给砼构件质量带来不利.本文强调了低温回火处理和机械消除应力方法,对消除应变时效有较好的效果. The strain aging of cold-rolled ribbed steel bars causes the strength of the steel bars to increase, and the elongation rate decreases, which brings disadvantages to the quality of the crucible components. This paper emphasizes the methods of low-temperature tempering and mechanical stress relief, and has a good effect on eliminating strain aging.
