Microstructure and ageing characteristics of a cast Zn-Al based alloy (ZnAl7Cu3) were studied using X-ray diffraction, electron scanning microscopy and back-scattered diffraction techniques. Two stages of phase transformation, i.e., decomposition of zinc rich η phase and four phase transformation, α + ε T′ + η, were detected during ageing at 150°C. Electron back-scattered diffraction technique was applied in distinguishing both zinc rich η and ε phases.
