摘要	In order to precisely describe the dendrite evolution during solidification process, especially in the micro-scale, a continuous model is adopted to solve the discontinuous physical properties between solid and liquid phases. In this model the physical properties in the interface zone are the average physical properties of solid phase and liquid phase, which can smooth their properties gap and make the properties continuous from liquid to solid phases. In addition, the averaged solute concentration is used to keep the solute conservation in the local interface zone. The simulated results show that this model can deal with the properties gap between the solid and liquid phases in the interface zone, and further simulate the dendritic growth, local interface instability, and appearance of the second dendrite arm, tertiary dendrite arm and the pattern of micro-segregation.
