摘要：
The present study first reports the application of multiple pulse treatment (MPT) for recrystallizaion of Mg-3Al-1Zn (AZ31) alloy strip. It is surprising and exciting that the completed recrystallization state of sample subjected to the electropulsing can be obtained rapidly in similar to 10 s at relatively lower temperatures compared with conventional heat treatment. MPT also features excellent mechanical property and typical ductile failure thanks to ultrafine grained microstructure. The favoring mechanism of recrystallization of MPT can be attributed to the coupled actions of the thermal and athermal effects, thereinto, the latter one activates dislocations climb effectively.
