Electrical conductivity and mechanical properties of the solid state recycled EN AW 6082 alloy

In the last few years there is a demand for development new technologies in order to increase scrap reuse potential and CO2 emission savings. This paper deals with novel aluminum recycling process using severe plastic deformation (SPD). Aluminum was recycled from machined chips without any remelting (solid state recycling-SSR) in order to reduce environmental pollution and to increase material yield during the process. Machined chips were cleaned, compacted and hot extruded. After hot extrusion semi-finished product (aluminum bar) was processed with equal channel angular pressing (ECAP) in order to improve mechanical properties and electrical conductivity. ECAP process temperature and the number of recycled samples pass through tool where varied. After SSR process electrical conductivity and mechanical properties of recycled samples were evaluated. The efficiency of the SSR process was confirmed and quality recycled samples were produced.
