Abstract Scope |
We present the Monte Carlo simulation methods for the microstructure evolution via various diffusion mechanisms. Firstly, a conservative Monte Carlo algorithm is explained using a two-phase coarsening example. Specifically, the coarsening behavior of nanoporous gold during annealing is compared to the simulation results. As the second topic, we discuss a new Monte Carlo method, developed to simulate the diffusion of the second constituent atom through the polycrystalline matrix. The method incorporates the effect of crystal anisotropy, the difference in grain boundary vs. bulk diffusion and the free energy calculation using a multi-scale approach. |
