Cellular Automata Simulation of the Ceramic Material Sintering Process with Sintering Additives

A grain growth simulation model for ceramic material sintering process with sintering additives based on cellular automata is constructed based on the grain growth driving force theory of grain boundary energy and the curvature of the grain boundary.The results show that the sintering additives on the grain boundaries have a strong pinning effect.The grain growth index of the ceramic material with sintering additives is lower than that without sintering additives.Add sintering additives can effectively refine the grains The simulation results are in good agreement with the microstructure of Al_2O_3/TiN ceramic materials with sintering additives.Cellular automata model is applicable to the grain growth simulation of the ceramic material with sintering additives in sintering process.
