Abstract

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′Sand η′Twith a small difference of about 1% in lattice parameters (c0/a0) were identified, based on the determined lattice parameters of the phases, and the reverse eutectoid phase transformations: η′T+e{open}′T+α′T→η′Sand e{open}+α→T′+η were successfully detected. Electron back-scattered diffraction appeared to be an effective technique for studying complex electropulsing induced phase transformations.
