| Abstract Scope |
Solid Phase Processing (SPP) can be used to recycle secondary aluminum alloys by mitigating the effect of impurities, like Fe and Si but the determination of optimal SPP-recycled alloy compositions and properties can be time-consuming. This study aims to speed the process of defining optimum SPP-recycled alloy composition by developing and demonstrating a new rapid screening methodology that can produce bulk-scale samples of materials with gradient impurity levels. Such a process will also facilitate a better understanding of the composition/microstructure/property relationships in alloys subjected to SPP through a wide range of compositions. Friction-based extrusion will be used to produce compositionally graded bulk materials having a continuous variation in composition from one end to the other. The gradient chemistry approach will be used to vary the levels of impurities such as Si, Fe, and Cu in aluminum and extracted samples will be tested for mechanical property response in strength and ductility. |
