| 摘 要： | 利用X射线衍射技术(ODF分析)并结合光学显微镜和透射电子显微镜观察了本溪钢铁公司生产的08Al深冲钢板的织构和组织,研究了预回复对其再结晶织构及组织的影响·结果表明:预回复退火具有推迟冷轧08Al深冲钢板再结晶的作用,但并未改变08Al深冲钢板的再结晶形成机制·08Al深冲钢板在预回复下再结晶γ纤维织构增强的原因主要是由于预回复降低了形变储能,抑制了其他取向晶核的形成及长大,促进了再结晶γ取向晶粒的择优生长

| Abstract: | Effects of pre-recovery on recrystallization texture andmicrostructure of deep-drawing 08Al steel sheet were studied by X-ray diffraction technique (ODF analysis)combined with both optical microscopy and TEM morphology. The results show that pre-recovery retards the recrystallization process and has no effect on the recrystallization mechanism. The possible reason for the enhancement of the γ-fiber texture is due to the release of deformation energy during pre-recovery,which promotes the growth of grains with γ orientation and restrains the growth of grains with other orientation. |
