Distinct role of eutectic morphology on the plastic flow in cast Mg–3Ca alloy

Discrete role of eutectic morphology on plastic deformation and damage accumulation in cast Mg–3Ca is elucidated. Alloy with lamellar eutectic exhibits higher hardening rate at strain <0.01 than partly divorced eutectic. Overall deformation behavior is rationalized as change in load transfer behavior dependent on eutectic morphology as in metal-matrix composites.
