We investigate the coarsening kinetics of two-phase microstructures using a diffusion-controlled Monte Carlo model. Here, we propose a new model that incorporates the control over the ratio of the surface diffusion rate to bulk diffusion rate during the coarsening of the bicontinuous system. In the case where surface diffusion is dominant, the model is found to mimic the coarsening of the ligaments of the porous metal system, which is different from well-known Kawasaki dynamics. To verify this new model, various measures for microstructural length scale are calculated in order to examine the existence of the steady state during coarsening and to extract the growth exponent as a function of diffusion rate ratio and system temperature.
