Size Refinement

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 increasing the number of ARB cycles.

Multilayered Composites

Mg/Al alloy multilayered composites were produced by accumulative roll bonding (ARB) technique. The microstructures of Al and Mg alloy layers were characterized by scanning electron microscopy, and damping capacity of the composite was tested by dynamic mechanical analyzer.It can be found that the diffusion layers were produced in Al and Mg alloy layers, and the diffusion layers increased with increasing of the ARB pass. With the increasing of ARB pass, the room temperature damping value of Mg/A1 multilayered composite presented a downward trend. The temperature damping spectrum of the composite had two internal friction peaks, with the increasing of the ARB pass, the peak height of P1 peak increased gradually and P2 peak moved to low temperature gradually.
