本文用塑性应变比R、△R值对Cr16Ni14带钢的成形性进行了评价。研究结果表明:工艺制度与R、△R值直接相关,当冷变形率为60～65%、固溶温度980～1000℃,可控制Cr16Ni14带钢的R=0.98～1.01、|△R|≤0.091的范围,带钢具有优良的成形性能,能有效地控制制耳、桔皮、裂纹等缺陷。同时还得出了LDR与R及织构取向强度相对成份I_(110)/I_(111)参量之间的相关性,通过数字统计分析得出R=0.98+logI_(110)/I_(111),LDR=1.79+0.28R,LDR=2.06+0.11logI_(110)/I_(111)的定量关系。
In this paper, the plastic strain ratio R, △ R value of Cr16Ni14 strip formability were evaluated. The results show that the process system is directly related to R and △ R values. When the cold deformation rate is 60-65% and the solution temperature is 980-1000 ℃, R = 0.98 ~ 1.01 can be controlled for Cr16Ni14 strip, | △ R | ≤ 0.091 range, the strip has excellent formability, can effectively control ear, orange peel, cracks and other defects. At the same time, the correlation between LDR and R and relative I / (110) / I_ (111) parameters of texture orientation strength was also obtained, and R = 0.98 + logI_ (110) / I_ (111) , LDR = 1.79 + 0.28R, LDR = 2.06 + 0.11logI_ (110) / I_ (111).
