Summary

In the present paper the coarsening process of initially fractal grain boundaries is modelled by two simulation techniques: the Monte Carlo simulation and the phase field method. While the Monte Carlo simulation (Potts model) is based on the statistical mechanics of discrete structural elements arranged on a regular lattice, the phase field method is based on a continuum diffusive interface model. A comparison of both methods for non-fractal coarsening processes has recently been reported in. In the present investigation the simulations are carried out for two-dimensional deterministic fractal grains and for an irregularly shaped real grain from a metallographic section.
