摘要： 重点研究了冷轧压下率对冷轧、再结晶织构的影响.结果表明:当终轧温度为750℃时,热轧带退火后以{111}再结晶织构为主.随着冷轧压下量的增加,γ织构减弱,α织构增强,{111}再结晶织构明显增强.当冷轧压下率为84%时,{111}再结晶组分的体积分数达到64.5%,退火板的平均塑性应变比(-R)高达1.69,平面各向异性(ΔR)仅为-0.17,深拉伸性能优良.

Abstract: The microstructure, texture and deep drawability of an ultra-low carbon/nitrogen ferritic stainless steel were investigated focusing on the influence of reduction on cold rolling and recrystallization texture. The results indicated that the hot-rolled strip after annealing is mainly characterized by {111} recrystallization texture when hot rolling is finished at 750°C. The orientation density of γ-fiber texture decreases but that of α-fiber texture increases with increasing cold rolling reduction. And, the orientation density of {111} recrystallization texture increases significantly as well. The volume fraction of {111} recrystallization component is up to 64.5% when the cold rolling reduction is 84%, and the cold-rolled sheet after annealing shows that its deep drawability is so favorable that the values of average strain ratio (R¯) and planar anisotropy (ΔR) are 1.69 and -0.17, respectively.
