In this study, fully annealed AA5083 type alloy sheets with 1 mm in thickness
were processed by accumulative roll bonding (ARB) at room temperature, up to 6 ARB
cycles. It was found that microstructure was refined and mechanical properties were
significantly improved with ARB processing. The maximum achieved values of
hardness and tensile strength were two and three times greater than that of the initial
material, respectively. This was attributed to the intensive strain hardening and grain
size refinement which occurred during ARB deformation. However, the uniform
elongation values were decreased by increasing the number of ARB cycles, and early
fracture was registered. SEM fractography of fractured surfaces after tensile tests
revealed a typical ductile fracture of ARB processed specimens, which was changed
with ARB deformation. It was observed that ductile area on the fractured surfaces and
the amount of necking, which occured before fracture, were decreased with increasi...ng
the number of ARB cycles.
