This work provides a mesoscopic study of the evolution of microstructure during normal
grain growth in the presence of particle dispersion. A Monte Carlo computer simulation
technique based on the Potts model has been developed which allows the evolution of
microstructure as a function of time to be followed in 2D. Dispersoids were modeled as
inert and static phases randomly distributed over the simulation surface. Three different
morphologies of dispersoids were considered and the results of the simulations were
compared with the results of simulations of grain growth in the absence of particles. A
strong pinning effect of dispersoids on moving grain bundles was observed. It was found
that as the particle concentration increases, both the final average grain sizes and the
time required for start pinning the microstructure decrease, which is consistent with the
results of experiments and simulations from the literature.
