摘要：Monte Carlo simulation method of microstructure evolution in nanocomposite ceramic tool materials is set up. Two-phased material systems with the same area fractions but various sizes of nano-particles are designed, and the processes of microstructure evolution are simulated. The influences of nano-particle size on microstructure and grain growth are observed and discussed quantitatively. It is found that the mean size of matrix grains increases with the increase of nano phase size during simulation, and intragranular-type microstructure is more difficult to form. The material Al2O3/nano-SiC is developed and the simulated results are verified.
