摘　　要：利用X射线衍射ODF分析方法,研究了电场对08Al深冲钢板单台阶退火和双台阶退火再结晶织构的影响.结果表明:电场提高了再结晶γ纤维织构的强度,同时降低了再结晶α纤维织构的强度.产生上述结果的主要原因是由于电场降低了各取向的形变储能,从而抑制了储存能小的取向晶核的形成及长大,促进了储存能大的再结晶γ取向晶粒的择优生长.The cold-rolled 08A1 killed steel sheets were treated according to the ' one-step annealing ' and ' two-step annealing ' schemes, under applying or not applying an electric field. The effects of electric field on recrystallization texture were investigated by X-ray ODF analysis. The results show that the electric field annealing may reinforce the 7-fiber texture and weaken the α-fiber texture. The most important reason is that the electric field decreases the driving force of recrystallization, which would hinder the nucleation and grain-growth on the whole. Therefore, the electric field annealing would promote the growth of the 7-oriented grains due to their relatively high storage energy, and restrain the growth of grains with the other orientations.
