| Abstract Scope |
There is an increased push to use secondary aluminum (Al) from different recycle streams as feedstock for the manufacture of automotive body components. An unavoidable shortcoming of secondary Al is the entry of impurity elements such as Si and Fe, and consequent deterioration of mechanical properties. However, previous research on wrought Al-Mg-Si alloys has shown that their formability and yield strength could be tuned by changing the Mg/Si ratio and heat treatments. At the fundamental level, these favorable property changes could be attributed to the underlying precipitate-dislocation/vacancy interactions in operation. In this study, we leveraged small-angle X-ray scattering during in-situ tensile loading to track the changes in solute cluster/precipitate volume fraction and size distribution in Al-6016 alloy as a function of applied strain for different recycled compositions, heat treatments and pre-strains. The insights gained from this study will help design the next generation of wrought recycled Al-alloys with improved processability. |
