Abstract: The second-phase particle has an important effect on grain coarsening kinetics and topology. The hinder phenomenon of second-phase particles is simulated using cellular automata algorithm(Cellular Automaton, CA) in the grain coarsening process. By CA algorithm, the evolution of coarsening kinetics, topology and morphology is simulated in the grain coarsening process of the second phase particle and the influence of temperatures and time on the coarsening process is also studied. The simulation results considering the second-phase particles show that grain coarsening kinetics exponent is close to 3, instead of 2;the coarsening of the grain has the same topological characteristics as those in ideal conditions, the edges number of grain 6 account for the largest proportion, followed by the pentagon and the heptagon; while the grain edges number of 3 or 10 grain is in very low proportion, around 5%;The morphology evolution in CA simulation of grain coarsening process shows that, with the increase in holding time or temperature, the average grain size increases. The simulation results have the same conclusions as that of related literatures, which ensure the reliability of the CA model in this article.
