Abstract
Dynamic electropulsing induced phase transformations and their effects on the plastic elongation of a furnace cooled ZnAl based alloy (ZA22) were studied by using backscattered scanning electron microscopy, transmission electron microscopy and electron back-scattered diffraction techniques. Under electropulsing, various transitional phases formed via the spinodal decomposition of AFC phase. Adequate electropulsing provided favorable identities of both microstructure and dislocation due to pinning dislocation by transitional phases and second phase precipitates. The mechanism of effects of dynamic electropulsing on elongation of the alloy was discussed from the points of view of microstructural evolution and dislocation dynamics.
