The microstructure simulation of castings is the use of computer to simulate the formation of microstructure of castings to predict the microstructure and properties of castingsIn this paper, the development and application status of microstructure numerical simulation of castings are reviewed The microstructure numerical simulation of castings is briefly introduced And the macro / micro unified mathematical model in the simulation, such as the heat conduction model, the solute transport model, the nucleation model and the grain growth model The two random methods, Monte-Carlo method and Celular-Automat method, are analyzed. Disadvantages Evaluation of the new technology used in the simulation On this basis, the current development direction of microstructure simulation of castings is proposed.
