Abstract

Electropulsing induced recrystallization of a cold-rolled Mg-9Al-1Zn alloy was studied using electron backscattering diffraction pattern (EBSD), transmission electron microscopy (TEM) and hardness test. The results indicated that compared with conventional heat treatment, electropulsing treatment (EPT) substantially accelerated recrystallization of the cold-rolled Mg-9Al-1Zn alloy within a short time of several seconds at relatively low temperature, as well as suppressed precipitation of β-Mg 17Al 12 phase. Based on the EPT enhanced atomic diffusion resulting from the coupling of the thermal and athermal effects with the direct electron-atom interactions, EPT accelerated recrystallization due to significantly increasing both the velocity of dislocation motion and subgrain growth rate. © 2012 Elsevier B.V.
