<p>IQueryn this study, the mechanical and tribological performance as well as the machinability of aluminium parts obtained by solid chip recycling were investigated and compared with the reference material. These aluminium billets were obtained using the stir consolidation friction technique, which consists of compacting chips from machined parts and rotating a cylindrical tool at different speeds. Different rotation speeds were used to produce the parts that were characterised. Chemical composition, microstructure, microhardness, machinability, friction and wear properties, and mechanical properties using the small punch test were measured and compared with the reference material. It was found that the microstructure of the recycled materials differed from that of the reference material. The latter has a microstructure of long grains oriented in the longitudinal direction, whereas the recycled materials have a microstructure of equiaxed fine grains, a microstructural evolution synonymous with dynamic recrystallisation. Hardness is more or less the same for recycled and reference materials and remains constant throughout the depth. The evolution of the coefficient of friction is similar but with a lower value for the recycled material in the stable part, whilst wear is lower by a factor of 2 for the sample obtained at 2000 rpm compared to the reference material. Finally, the sample obtained at 2000 rpm has a mechanical strength 25% lower than the reference material but with the same ductility.</p>
