Abstract: A three-dimensional parallel implementation of a Monte Carlo model for the microstructure evolution during sintering is presented. The model accounts for the main phenomena occurring during sintering, including grain growth, pore migration and vacancy annihilation. The parallel implementation is based on the SPPARKS code and enables the simulation of systems with large number of particles. Several examples are shown and results are compared with a serial implementation as well as experimental data available.

Keywords: analysis; modelling; numerical techniques; kinetic Monte Carlo simulation; KMC simulation; sintering; microstructure; grain growth; pore migration; vacancy annihilation.
