Abstract

Computer simulation of grain growth in the presence of a liquid phase was done using Monte Carlo methods. The results were compared to validation experiments using aluminum nitride (AlN) ceramics as the model materials. The grain size calculated from the simulated microstructures decreased as the volume fraction of the liquid phase increased. The cube of the average grain size was found to be proportional to both the number of Monte Carlo steps (MCS) and the annealing time for the model experiments. Consequently, it was confirmed that Monte Carlo methods could be used to predict grain growth in a typical ceramic/liquid phase system.
