Simulation of the Effect of Sintering Temperature on Microstructure Evolution in Nanocomposite Ceramic Tool Materials
Abstract:
A Monte Carlo Potts model coupled with sintering temperature for the sintering process of nanocomposite ceramic tool materials is proposed, the relation between grain growth and sintering temperature is presented. The grain growth process at different sintering temperature is investigated in this model, and the effect of sintering temperature on microstructure evolution is discussed, it is found that the mean grain size increases with the increase of sintering temperature during simulation, and nanoparticles are easier to enter into matrix grains to form intragranular-type microstructure at higher temperature. The simulation results are in accordance with the experimental observations.
