Abstract Scope |
6xxx series aluminum alloys were mainly used for automobile exterior panels due to its advantages such as appropriate strength, excellent formability, corrosion resistance and dent resistance. Recently, demand is increasing due to the issue of weight reduction for the purpose of improving fuel efficiency, and accordingly, better aging hardening characteristics and research are required.
In this study, changes in the amount of Mg-Si-based precipitates, which are the main reinforcing phases of 6xxx-based aluminum alloys, and the changes in mechanical properties were investigated according to the change in the Mg content. Quantitative changes in precipitates according to differences in Mg content were predicted by the phase analysis software (JMatPro13.0). By different pre-aging conditions for each composition, the behavior of hardness and strength change according to temperature and holding time and BH characteristics were investigated to investigate changes in mechanical properties. |
