Abstract

The effect of electropulsing treatment (EPT) on the microstructure evolution and the mechanical properties of rolled AZ31 magnesium alloy was studied. The recrystallization of the deformed AZ31 magnesium alloy was accelerated by EPT with high current density and low duty ratio. EPT with different parameters was analyzed. The thermal and athermal effect of EPT was researched and the mechanism of the recrystallization under EPT was also revealed. The results indicate that after EPT with a pulse-width of 20 μs, a current density of 3.508×10⁹ A/m², a duty ratio of 0.002 and processing time of 5.5 min, recrystallization occurs due to the athermal effect, the average grain size of AZ31 alloy is refined from 72 μm to 2 μm, the tensile strength is 295 MPa, and the elongation is 20%.
