In the present effort, enhancement of mechanical properties of Aluminium alloy, Al6061, due to cold-rolling is compared with that due to peak-ageing. Heat treatable Al6061 was cold-rolled with different pre-rolling conditions. Since different peak-ageing conditions are given in literature, a systematic study was conducted to determine the peak-ageing conditions for the procured aluminium alloy. Micro-Vickers hardness tests as well as uniaxial tensile tests were conducted to evaluate the mechanical properties. Cold-rolling to higher thickness reductions resulted in a significant improvement in hardness and tensile strength as compared to peak-aged samples. Artificial peak-ageing before cold-rolling did not have a significant effect on the properties after cold-rolling. Enhancement of properties was comparable to the more complex severe plastic deformation process of cryo-rolling followed by warm-rolling. Cold-rolling could be used as a simpler and effective method to enhance mechanical properties of Al6061. No significant difference was found in the tensile strength between rolling and transverse directions. © 2017 Elsevier Ltd.
