| Abstract Scope |
Among different Al alloys, the Al 6xxx series alloy has relatively high strength and good formability compared to other Al alloys. The microstructure and texture evolution of Al alloys of the 6xxx series depend on the starting microstructure, texture, and the shape, size, and distribution of precipitates. Further, different loading conditions significantly affect the microstructure and texture evolution. Hence, it is important to optimize the given microstructure under specific loading conditions. In this work, experimental microstructural data and stress-strain curves were used to calibrate an in-house crystal plasticity model for the 6xxx series Al alloy. Subsequently, using an in-house synthetic microstructure code, different synthetic microstructures were generated by varying grain texture and morphology. The calibrated model was used to simulate tensile loading conditions. Finally, the underlying mechanisms driving the evolution of microstructure, texture, stress localization, and stress-strain behavior across the different microstructures are analyzed in the present paper. |
