Abstract:The 3D fluid turbulence model was used to simulate the friction stir welding process.Three-dimensional Monte Carlo model was then applied to simulate the grain growth in the welding zone.The comparison with experimental data shows the validity of the proposed model.The grain evolution in the stirring zone was simulated by combination of the movements of material particles and temperature histories in the fluid model and the grain growth model.Results indicate that the grain size at advancing side is larger than the retreating side,which agrees well with the experimental observations.The grain structure in the stirring zone can be three dimensionally revealed,which is hardly directly revealed in experiments.This work can be beneficial to the quantitative understanding of the morphology and sizes of the grains in stirring zone in friction stir welding.
