Abstract: A computer simulation coupled with fabrication parameters for the sintering process of two-phase ceramic tool materials has been developed using a two-dimensional hexagon lattice model mapped from the realistic microstructure. The relationship between fabrication temperature and microstructure evolution, fabrication pressure and microstructure evolution is proposed respectively. The mean grain size of simulated microstructures by Monte Carlo Potts model integrated with fabrication temperature and pressure increases with an increase in fabrication temperature and pressure, which is consistent with the experiment results. The microstructure evolution of ceramic tool materials during fabrication is simulated by the new Monte Carlo Potts model with considering technology parameters.

Keywords: simulation; hot-pressing sintering; ceramic matrix composites; CMC; microstructure; Monte Carlo model; ceramic tool materials.
