Abstract Scope |
This research investigates the feasibility of directly recycling aluminium AA6005-T6 chips derived from the machining of high-speed train chassis at Hitachi Rail, addressing key environmental and industrial challenges. The primary goal is to reduce vehicle weight and lower CO2 emissions through a sustainable manufacturing process. The study involves the compaction of aluminium chips into billets, followed by extrusion. Laboratory analyses included density determination via tomography, hardness tests, and metallographic examinations to evaluate the mechanical and microstructural properties of the recycled aluminium. A comparative Life Cycle Assessment (LCA) was conducted to assess the environmental impact of the direct recycling process versus traditional recycling methods. The findings highlight potential energy savings and environmental benefits, supporting the viability of this recycling approach for industrial applications. |
