Abstract

Microstructure and phase transformation of a cast Zn-Al-based alloy (ZnAl11Cu3) are studied during ageing using X-ray diffraction and back-scattered scanning electron microscopy techniques. Decomposition of a zinc-rich η′s phase is observed to take place in the way of continuous precipitation. A four-phase transformation, α + → T′ + η, occurs during prolonged ageing. It is found that the phases involved in the phase transformation can be distinctly identified by using different atomic contrasts in the back-scattered scanning electron image of precipitates.
