摘要：

The electroplastic effect on Fe-6.5 wt% Si with intermetallic ordered phases was studied through a tensile test under electropulsing (EP). Air cooling was employed during the deformation to keep a low temperature to minimize the Joule heat effect. Under EP, the fracture elongation increased dramatically and the yield strength decreased compared to the non-EP samples. As the ductility improved under EP, the microstructure deformation degree increased, and the volume fraction of ordered phases B2 and D03 decreased. The dislocation configurations after EP tension were mostly paralleled. The results were discussed from the anisotropic effect of electropulsing.
