Abstract

Deformation behavior of a Mg72Cu5Zn23 alloy containing bimodal eutectic structure has been systematically investigated based on microstructural changes upon different amounts of compressive strain. The microstructural evolution of the sample at the early stage of the deformation up to 3% strain reveals that a large number of twins form homogeneously in the α-Mg phase of the coarse eutectic structure. After further deformation to failure, propagation of cracks takes place along the interface between the fine and coarse eutectic structures forming a typical dimple-like morphology on the fracture surface, indicative of the effective dissipation of the stress.
