| Abstract Scope |
The challenge of acquiring critical materials calls for innovative strategies that extend lifecycles and enhance performance. Solid phase alloying and upcycling offer a sustainable solution by converting mixed-metal waste into high-value alloys without melting. We present a one-step friction extrusion process that combines mixing, consolidation, and extrusion, using plastic deformation and localized heating to drive phase formation and microstructure homogenization. Key process parameters—temperature, strain, and strain rate—govern material flow, diffusion, and strengthening mechanisms. In aluminum systems, the upcycled alloys exhibit superior strength and ductility compared to their precursors, while reducing energy use by up to 95 %. Advanced characterization reveals nanoscale precipitates and uniform microstructures, confirming the process's ability to tailor composition and properties. This method supports circular economy goals by minimizing waste, simplifying manufacturing, and enabling scalable production of additive manufacturing feedstocks. This work bridges solid-state fundamentals with practical upcycling strategies to accelerate adoption in sustainable alloy development. |
