A brief overview is given of the influence of the input parameters on the simulated microstructure development in Monte Carlo simulations for monophase materials and for materials containing static second-phase particles. The second phase particles do not participate in interaction processes of the grain growth during ceramics sintering or metal annealing. It is commonly known that both these processes are accompanied with secondary recrystallization. On the other hand, they influence microstructure and thus desired properties of the final product. In the work we considered the second phase particles of various forms (granules, whiskers, fibers) with different mechanical properties, melting temperature and polycrystalline structure other than basic material. We assumed that their properties are irrelevant for the grain growth. The presented simulation examples illustrate how the input simulation parameters can influence the resulting structure and hence its properties.
