Summary Multi‐phase identification and phase transformations in electropulsing treated Zn–Al based alloy wire specimens were studied using electron back‐scattered diffraction, back‐scattered scanning electron microscopy and X‐ray diffraction techniques. By using electron back‐scattered diffraction, two phases: η′ S and η′ T with a small difference of about 1% in lattice parameters ( c 0 / a 0 ) were identified, based on the determined lattice parameters of the phases, and the reverse eutectoid phase transformations: η′ T +ɛ′ T +α′ T →η′ S and ɛ+α→ T ′+η were successfully detected. Electron back‐scattered diffraction appeared to be an effective technique for studying complex electropulsing induced phase transformations.
