3D Modeling and Visualization of Polycrystalline Material Microstructure at Grain Scale with Time Scale

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 Potts-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 visualization 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.
