The effects of static electropulsing on the phase transformations and elongation of a cold-deformed Zn-Al based alloy wire (ZA22) were studied using scanning electron microscopy (SEM) and electron backscattered diffraction (EBSD) techniques. Based on the transmission electron microscopy (TEM) determined lattice parameters of the phases involved, the electropulsing induced circular phase transformations were detected in the alloys using EBSD, which were never reported in any thermal and thermomechanical treated alloys. An adequate static electropulsing favored improving the identities of dislocation and microstructures (including the precipitation of the second phase, the residual stress, etc.), which resulted in enhancement of the plastic elongation of the alloy.
