Abstract
The densification and grain growth during sintering of alumina-zirconia (Al2O3ZrO2) ceramics were simulated using a modified phase field method, which considered simultaneously a density field, a composition filed and orientation fields. The results indicate that the model can capture the main microstructure features in the different stages of sintering. A higher relative green density leads to a higher final density and a larger final grain size in the sintered ceramics. A higher volume fraction of the ZrO2 phase results in a lower relative density and a smaller final grain size.
