Sažetak
This article deals with the direct recycling of EN AW 2011 aluminum alloy chips, which are formed by turning, into semifinished products using forward hot extrusion process. Direct recycling without re-melting is usually called solid-state recycling. The main aim of this article is to investigate the influence of depth of cut (size of chips) in the aluminum alloy turning process, extrusion temperature, and compaction force on mechanical properties, surface roughness, and extrusion force of recycled samples. An original approach to solve this problem is mathematical modelling of the process using the design of experiments. The influence of main research factors on yield strength (Rp0, 2), hardness (HV), extrusion force (F), and surface roughness (Ra) of recycled samples has been studied. The study has shown that the most influential factor on mechanical properties, surface roughness, and extrusion force was extrusion temperature.
