Abstract

The structural and high durability components in automobile and aerospace industries are mostly produced using nano-crystalline and ultrafine-grained (UFG). In this work, two different material, 99.99% pure aluminium and 99.99% pure copper were processed by the Severe Plastic Deformation (SPD) technique also known as Accumulative Roll Bonding (ARB) technique. During the ARB process, the metal sheet surfaces were stacked on top of each other and rolled together with a thickness reduction of 50% per cycle. The material subjected to very high plastic shear deformation showed the start of UFG microstructure to develop. An increasing trend of hardness was observed with increase in number of reduction cycles for ARB processed Al-Al, Cu-Cu and Al-Cu sheets. However, ARB processed oxygen free (OFE) copper showed slightly different ductility behaviour in comparison to other ARB processed materials.
