A novel two‐dimensional (2D) micromechanical model presented is capable of predicting eutectic network strength and structural efficiency consistent with computed results on the basis of three‐dimensional (3D) actual morphology of eutectic network, and shows considerable advantages in terms of efficiency, practicability and computation cost. Another critical advantage lies in the capability of evaluating network‐matrix interaction and the incorporation of interaction strength leads to an improved agreement between numerical and experimental flow behavior of the Mg alloy. The analysis also suggests that network‐matrix interaction is comparable with dispersion and network strengthening with respect to the contribution to alloy yield strength.
