The study of the microstructure evolution of nano/meso-porous metal using the Monte Carlo simulation / A finite element method simulation of the stress distribution on the grain boundaries in a three-dimensional polycrystalline microstructure under uniaxial loading

Abstract

Using the Monte Carlo simulation, we investigated the microstructure evolution in a nano/meso-porous metal. Monte Carlo Potts model have been carried out microstructural evolution of two-phase polycrystalline materials in which grain growth is controlled by grain boundary diffusion. We used Kawasaki-like dynamics and Metropolis acceptation probability, which ensures the evolution towards equilibrium. Evolution of the simulated microstructures is different morphology depending on the MCS(Monte Carlo step), domain temperature, grain boundary energies and heterophase interfacial energies. Also, we compared to simulated and real nanoporous metal microstructure.
