Advances in Microstructure Simulation of Casting Alloy

The numerical modeling of solidification process is moving from macro-to micro-modeling.Micro-modeling can not only predict the solidified microstructure of materials but also provide accurate information on latent heat releasing for macro-modeling.In the paper the state-of-the-art of microstructure simulation is given in order to describe the main methods of micro-modeling,such as deterministic,stochastic and phase-field modeling,etc.Finally the existing problems and the future tendency are analyzed.
