通过工艺控制得到含不同γ纤维织构份额的430铁素体不锈钢样品,研究了γ纤维织构份额对430不锈钢表面起皱程度的影响。结果表明:将冷轧430铁素体不锈钢在略低于再结晶温度下长时间保温,然后进行高温再结晶退火处理能够获得高份额的γ纤维织构;随着显微组织中γ纤维织构份额的提高,430铁素体不锈钢表面抗起皱性能增强。相比于{100}<011>和{112}<110>取向晶粒,γ纤维取向晶粒平均塑性应变比高,并能在再结晶组织中较少形成取向相近的晶粒簇,减轻了铁素体不锈钢的表面起皱现象。
The 430 ferritic stainless steel samples containing different γ fiber texture fractions were obtained through process control. The effect of γ fiber texture proportion on the degree of surface wrinkling of 430 stainless steel was studied. The results show that a high proportion of γ fiber texture can be obtained by cold rolling 430 ferritic stainless steel for a long time under a little lower than the recrystallization temperature, and then performing high temperature recrystallization annealing treatment. With the γ fiber texture in the microstructure Increased share, 430 ferritic stainless steel surface wrinkle resistance enhancement. Compared with the {100} <011> and {112} <110> oriented grains, the average plastic strain ratio of the oriented grains of the γ fiber is high, and fewer grains with similar orientation are formed in the recrystallized structure, reducing Ferritic stainless steel surface wrinkling phenomenon.
