%X A set of mathematical and physical models has been proposed to describe the mi-crostructure evolution in solidification process of the AZ91D die casting magnesium alloy, which is a modified 3D micro-scale cellular automaton (CA) model coupled with 3D model of solute concentration field. For multi-grains growth simultaneously, this model successfully revealed the whole evolution process of solute diffusion among the primary grains, solute enrichment and the eutectic transformation. The improved model was applied to simulate the microstructures of different parts of the actual AZ91D die casting, and the simulation results are in good agreement with the experimental ones.
