| Abstract Scope |
The production of industrial by-products is a persistent issue that has plagued the economics and sustainability of manufacturing throughout history. We propose a methodology wherein low value rare earth element (REE) waste products may be repurposed to develop high performance products with exceptional value, thereby increasing REE production and decreasing the criticality of other REE. Al-REE alloys are an emergent material with the capability to push boundaries of performance, especially in weight critical applications like transportation. The exceptional castability and thermal stability of Al-REE alloys enable performance outside of normal limits of Al alloys. Here, we discuss how this alloy can address REE supply imbalances and the potential impacts of deployment of Al-REE deployment on the diversity of REE production. Associated opportunities for improvements to existing Al recycling streams by the introduction of this material will also be discussed. |
