Sažetak

An improved two-dimensional Q-State Monte Carlo Potts model for describing anisotropic growth of grains of ceramics is established. The sintering additives, pores, and second-phase particles introduced into the ceramic matrix have been fully considered in the new algorithm. Using this model, the influence of the second-phase particles on the microstructural evolution of ceramics with elongated grain morphology are investigated. Results show that the addition of the second-phase particles obviously hinders the anisotropic growth of grains, thereby resulting in a slightly decreased average grain size and grain growth exponent. The preliminary investigation indicates that the simulation results are in good agreement with the existing sintering kinetic theory.
