In this work, accumulative roll bonding ARB process as a severe plastic deformation was applied on an AA5083 sheet up to 6 cycles at the temperature of 300℃ and at the strain rate of 50 s­‐1. The results of tensile tests show that the values of the yield stress and the ultimate tensile strength don-t change considerably after 4 cycles. Also, transmission electron microscopy TEM micrograph confirmed that the microstructure has fine sub grains with the size of 200 nm - 400 nm.
