摘要：
AZ31 magnesium alloy strips have been cold-rolled to thickness reduction of 33% and followed by electropulse treatment (EPT) with different current parameters for 7 s and furnace annealing for comparison. The results indicate that recrystallization is drastically accelerated by EPT and continuous recrystallization induced by EPT is strongly dependent on the current. Deformed coarse-grain boundaries together with extension twins (ET) bands provide sources for nucleation and are gradually consumed by recrystallization. A double peak texture was generated after recrystallization, which is associated with the promoted non-basal nucleation and the non-basal dislocations activities. (C) 2015 Elsevier Ltd.
