RESUMO:

The present work presents the study of obtaining and characterizing the recycling of aluminium from the beverage cans scrap composed of AA3004, 5042 and 5182 aluminium alloys through high energy milling and powder metallurgy. The cans were selected, drilled and milled to obtain the metallic powder under different milling times (1h, 1h30min and 2h). Each powder obtained was compacted at a load of 500 MPa and sintered at 600 ° C for two hours. To characterize the aluminium powders, SEM, EDS, XRD and laser granulometry analyzes were performed; while the material consolidated by sintering, in addition to SEM, EDS and XRD analyzes, were also characterized by Vickers dilatometry, compression and microhardness tests. The samples presented variations in your mechanical properties as a function of milling time. The particle size and its relationship with the properties of the aluminium alloy were evaluated; The phases formed due to the chemical composition of the alloy were also observed. The processing route adopted resulted in the effective compaction of the samples.
