On the effect of SPD on recycled experimental aluminium alloys: Nanostructures, particle break-up and properties

As a part of on-going research on the effects of recycled alloy chemistries on alloy design, properties and applications, the present work focuses on SPD processing. ECAP is used to deform two different Al alloys with “recycled alloy chemistry” and a standard AlMgSi alloy. A comparison between deformation routes A and BC is performed to evaluate the effects of deformation path on particle break-up and particle distributions. Both alloy content, amount of accumulated strain and choice of deformation route influenced particle refinement.
