Accumulative Roll Bonding (ARB) is a severe plastic deformation technique used to enhance the mechanical properties of metallic materials through repeated rolling and bonding cycles. In this study, the influence of processing temperature on the mechanical properties of Al 6061 alloy during ARB was investigated. ARB processing was performed at varied temperature (100 °C and 200 °C) and the processed sheets were characterized for tensile properties and Hardness evolution. Results showed that 200 °C processing temperatures facilitate dynamic recovery leading to coarser grain structures but enhanced ductility. However, 100 °C temperature promote greater strain hardening and finer grains resulting in higher ultimate tensile strength. These findings provide insights into optimizing ARB processing parameters for Al 6061 alloy to achieve desired combinations of strength and ductility.
