Abstract
In order to promote aluminum scrap recycling and reduce remelting losses, solid-state recycling processes are subject to increasing academic attention. These processes range from severe plastic deformation (SPD) to diffusion-based processes like field-assisted sintering (FAST). In this study, a FAST-based recycling route consisting of precompaction, FAST, and impact extrusion of dry machined EN AW-6082 and EN AW-7075 aluminum chips was used to create multi-material parts from different aluminum alloys. To examine the effect on the resulting part quality, two different hybrid material layouts were created during cold compaction of the chips. The subsequent sintering process took place in a field-assisted sintering (FAST) machine at 400°C and 500°C for a duration of 5 min under a pressure of 85 MPa, allowing for the analysis of inter-chip diffusion. These sintered blanks were then cold-formed by impact extrusion. Metallographic and computed tomography analyses as well as hardness measurements were performed for property evaluation before and after heat-treatment.
