Monte-Carlo Simulation of Isotropic and Anisotropic Grain Growth in Liquid Phase Sintered Ceramics
The Potts-Monte-Carlo Method was used to study the isotropic and anisotropic grain growth and coarsening process in liquid phase sintered ceramic materials. The program was made ourselves and so its convenient to modify duly. A fully wetting system was assumed and the interpretation of the simulation results will be described and discussed. A two dimensional, hexagonal lattice is developed to digitize the microstructure; the components and the grain orientation are distributed randomly. The periodical boundary condition is applied. The effects of liquid phase fraction raging from 0 to 0.20 and the isotropic and anisotropic growth mechanism were investigated. Its found that the isotropic grain growth mechanism is consistent to Ostwald ripening theory, the anisotropic factor results in significant influence on the grain morphology and the liquid fraction also affects the grain morphology, which were consistent with theoretical analysis and experimental investigation from others.
