Abstract Scope |
Age hardenable Al-Mg-Si(-Cu) alloys have been widely used in automotive industries because of their good strength-ductility balance and excellent formability. The stregnth of these alloys can be greatly improved by nano-scale precipitates during againg, and previous work has mainly investigated the relation between these main strengthening precipiates and mechanical behavior of 6xxx series aluminum alloys. However, it has less been focused on the role of minor alloying elements on precipitate formation and mechanical behavior 6xxx series aluminum alloys.
In this study, the precipitates and mechanical properties of 6xxx series aluminum alloys were analyzed by varying contents of additive alloying elements such as Mg, Si, Cu, Fe, and Mn. The phase of the alloys were quantitatively predicted by the phase analysis software, and the prediction results were compared with the microstructural analyses. The role of minor alloying elements on precipitate formation and mechanical behavior 6xxx series aluminum alloys will be discussed. |
