| Abstract Scope |
Wrought aluminum products at the end of their life cycle are generally downcycled to cast alloys. Instead of downcycling, recycling of these products for new wrought alloys can provide significant economical as well as environmental benefits. Hence, understanding the influence of increased alloy additions in the recycled wrought aluminum alloys is an important step towards achieving a circular economy of the wrought aluminum products. Therefore, we systematically increased copper, magnesium, and silicon content in the 5XXX and 6xxx alloys. The micro-segregation of these elements in the as-cast alloys and dissolution kinetics of the constituent phases during the homogenization processes is then studied. Finally, microstructural characteristics and dynamic recrystallization of the high recycled content alloys during the hot deformation is analyzed. Additionally, analytical models are developed for the micro-segregation of alloying elements which can be used for the assessment of solute segregation in a range of recycled aluminum alloy compositions. |
