The influences of dislocation magnification due to plastic deformation and solute atoms concentration on the electroplastic effect were investigated. It is found that the dislocation magnification due to plastic deformation will enhance the electroplastic effect. The electroplastic effect of Al-Cu alloy was enhanced with the increase of plastic deformation and current density. Moreover, the solute atoms concentration has a great effect on the electroplastic effect. The influence of electrical current pulse on Portevin-Le Chatelier (PLC) effect of Al-Cu alloy is also reported.
