【Abstract】 Several representative methods for the microstructure simulation of casting solidification are enumerated firstly, and then, the improvement and application of the methods in recent years are discussed and appraised objectively in this paper. At the same time, a new method for unidirectional solidification-3D dendrite envelop tracking method is introduced, it is used for the production of the special parts which are sensitive to the presence of defects. Finally, the problem to be faced and tendency in the field are pointed out.更多还原
