Abstract Scope |
During friction stir welding (FSW), the primary recrystallization mechanism is dynamic recrystallization (DRX), where nucleation and grain growth of new grains develop during the deformation process. For simplification, we modeled FSW by employing static recrystallization, simulating grain growth with discrete nucleation where the initial grains will have an assumed amount of deformation energy. The phase-field method was used to simulate this metallurgical procedure, emulating the microstructural evolution of friction stir welded 316 stainless steel. The resulting microstructure of FSW samples is largely defined by temperature behavior and secondary phase particles; therefore, our model focuses on these critical controlling factors in FSW nucleation and grain growth. For validation, we compare our simulation results to experimental findings found in literature. |
