| 摘 要： | 采用基于Monte Carlo Potts模型的仿真技术对单相多晶体各向同性晶粒组织进行了三维建模，利用OpenGL图形接口，在所建多晶体组织模型数据结构的基础上进而实现了三维可视化和任意角度观测，结果表明，所建几何图像模型可以很好地仿真预定细观组织结构参数的三维多晶体组织，不但满足模型化研究所要求的统计意义上的准确性，而且非常符合实际材料显微组织的多变性特征，可望用作细观尺度多晶材料加工过程数值模拟和细观力学计算的基本组织模型。

| Abstract: | Microstructure evolution of polycrystalline materials plays an important role on properties of materials. 3D modeling of microstructures of polycrystalline materials is implemented using Monte Carlo Pot- ts-model simulation. The modeling includes many microstructural parameters, such as grain size and grain size distribution, grain shape, grain orientation, properties of grain and grain boundary. Three-dimensional visual- ization of so-constructed microstructures is further carried out. The results show that these models can simulate polycrystalline microstructures with various parameters, and can be used as meso-scale models of numeric simulations of processes and of meso-mechanics computation for polycrystalline materials. |
