摘　　要：利用所建立的热动力学相场模型,在计算机上编制出三维组织凝固模拟程序,在统一的相场方程和温度场方程耦合下,实现了三维工业纯铝枝晶生长模拟,并给出了模拟结果。Using the established thermodynamic phase field model, the computer simulation program has been programmed to simulate the three-dimensional crytals treeing during the solidification. In the coupling of the phase field equation and the equation of temperature field, the dendrite growth simulation of three-dimensional industrial pure aluminum was realized. And the simulation results were given.
