Computer simulation of grain growth with mobile particles

A Monte Carlo simulation procedure is employed to study grain growth in the presence of diffusing particles. In particular, attention is given to the temporal evolution of the grain size and microstructure and the influence of the particle fraction and temperature. The results are analyzed in terms...

Summary:A Monte Carlo simulation procedure is employed to study grain growth in the presence of diffusing particles. In particular, attention is given to the temporal evolution of the grain size and microstructure and the influence of the particle fraction and temperature. The results are analyzed in terms of the relationship between the boundary driving force and the steady state boundary velocity. The observed kinetic behavior, growth exponents, and depinning time are in agreement with a simple theoretical model with different mobilities for boundaries with and without attached particles.
