| Abstract Scope |
As scrap aluminum becomes more available, producing energy-efficient secondary aluminum offers a cost-effective alternative for aluminum producers. Before extensive use in wrought alloy production, it is crucial to study how increased recycled-alloy content affects processing. This study focuses on the automotive body sheet alloy AA5754, which has elevated levels of iron (Fe), copper (Cu), and silicon (Si). Both the particle size and volume fraction of the Fe-rich and Mg-rich phases retained after homogenization in the HRC alloys are higher than in the baseline alloy. Texture analysis after hot plain-strain compression indicates that, with increased solute and secondary particle content, the cube component decreases, whereas the Goss, ND-cube, and random components increase. Increased particle retention in the HRC alloys may enhance particle-stimulated nucleation, thereby influencing the texture of the recrystallized grains. This quantitative characterization will facilitate the optimization of recycled alloy content, parameterization of their processes, and multi-physics modeling and simulation. |
