  • Title: Use of EBSD to study electropulsing induced reverse phase transformations in a Zn-Al alloy (ZA22).
    Author: Zhu YH, To S, Liu XM.
    Journal: J Microsc; 2011 Apr; 242(1):62-9. PubMed ID: 21118233.
    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'(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.
