摘要In order to reflect the characteristic of sharp interface during the dendritic growth process, cellular automaton method is used to simulate the dendrite evolution. In this method the different physical properties in both solid and liquid phases are adopted to reflect the different heat-transfer rate. The simulated results show that there is solute micro - segregation between the two primary dendritic arms. In addition, the solute concentration gradient and temperature ahead of the solid/liquid interface decrease gradually with increasing solidification time. Comparing the simulated radius of the dendritic tip with the theoretical radius, we obtain that the simulated results fit the theoretical radius well, and the deviation is less than 1mum.
