State-of-the-Art for Casting Microstructure Simulation

Simulating the forming process of microstructure of castings by computer can forecast the microstructure and property of castings. The developing process of microstructure simulation and its application are discussed. The basic methods and the macro-micro mathematical models, such as the heat conduction model ,the transmission solute and modeland the crystalline growing model, are analyzed. The new techniques used in this field are evaluated. Based on these, the tendency and prospect of microstructure simulation of casting is discussed.
