Abstract Scope |
In future sustainable manufacturing, scrap recycling plays a role in reducing emissions. Traditional recycling methods often result in materials with lower performance than the original material. By melting and introducing additives, properties can be improved via chemical composition. However, the high temperatures and complex steps of traditional processes consume substantial amount of energy. Solid Phase Processing (SPP) has provided a high performance, low energy avenue to produce and recycle alloys. Solid phase alloying has been developed to combine consolidation, alloying, and extrusion into one step. For the first time, we converted alloy scrap into a different alloy by the friction extrusion process. AA 6063 machining chips were mixed with Copper, Zinc and Magnesium addition and extruded into 7075-like rod. After 7075-T6 heat treatment, the rod reached the same hardness and strength comparable to a standard AA 7075. Microstructure characterization reveals the alloying evolution in SPP, including dispersion, diffusion and precipitation |
