摘要
研究了不同硼的质量分数的低碳钢盘条的应变时效,结果表明:低碳钢中加硼可使因静态应变时效引起的线材屈服强度增加值略有降低;低碳钢中硼的质量分数为0.002 9%,同时[B]s/[N]<0.4时,对线材的动态应变时效影响不大;硼的质量分数在0.005%~0.010%的范围内,[B]s/[N]≥1.0时,可显著降低因动态应变时效引起的线材抗拉强度的增加值,因而改善了低碳钢盘条的拉拔性能.
The strain aging of boron containing low carbon steel wire rods was studied. The results show that adding appropriate boron in low-carbon steel could slightly reduce the increment of yield strength, which is caused by static strain aging. The increase of tensile strength caused by dynamic strain aging was hardly reduced while [B]s content was below 0. 002 9% and [B]s/[N]〈0.4. The increase of tensile strength caused by dynamic strain aging could be decreased obviously when [B]s is in range of 0. 005% to 0. 010% and [B]s/[N]≥1.0,so that the drawing perform ance of low-carbon steel wire rods could be improved.
