中文摘要：
有限元素细胞的自动机咖啡馆方法被用来在团结过程模仿 3D 微观结构，这被分析。基于这个方法， 9SMn28 的 3D 微观结构免费切的钢在团结过程被模仿，模拟结果与试验性的一致。另外， Gaussian 分发参数的效果也被学习。模拟结果显示出那越高吝啬的 undercooling，越 larger，并且越多更大圆柱的树突地区最大的成核密度，更小谷物的尺寸。越大标准差，最小的谷物的数字是越少。然而，一致性度首先减少，然后逐渐地增加。
英文摘要：
It was analyzed that the finite element-cellular automaton （CAFE） method was used to simulate 3D-microstructures in solidification processes. Based on this method, the 3D-microstructure of 9SMn28 free-cutting steel was simulated in solidification processes and the simulation results are consistent with the experimental ones. In addition, the effects of Gaussian distribution parameters were also studied. The simulation results show that the higher the mean undercooling, the larger the columnar dendrite zones, and the larger the maximum nucleation density, the smaller the size of grains. The larger the standard deviation, the less the number of minimum grains is. However, the uniformity degree decreases first, and then increases gradually.
