Investigation of Microstructure andAnisotropy of MechanicalProperties of the ARB-Processed Commercial Purity Aluminium with Interpassing Heat Treatment Abstract Accumulative roll bonding (ARB) is a severe plastic deformation (SPD) process that may be defined as multistep rolling process in order to create high strength metals with ultra-fine grained (UFG) in nanometer level. In this study,ARB process with interpassing heat treatment was carried out on the commercial pure Aluminium sheet up to 13 cycles.The variation of microstructure during the cycles of ARB process to access to grains with nanometer dimensions was investigated. In addition, micro-Vickers hardness measurement was carried out throughout thickness of the ARB processed sheets. Eventually, the changes of strength and elongation and also anisotropy of mechanical properties of the sheets during the cycles of process was studied by uni-axial tensile test in 3 directions (roll direction (RD), transverse direction (TD) and direction of 45o toward RD). Keywords: ARB Process, Nanostructure, Micro-Vickers Hardness, Mechanical Properties, Anisotropy.
