“…In the way, we have not necessarily to utilize the same materials in ARB process. The ARB of the dissimilar materials rather than the same ones has been recently studied actively [16][17][18][19][20]. This modified ARB has a merit to be able to fabricate various metal/metal multi-layer composite materials.…”

A multi-layered complex aluminum alloy was successfully fabricated by three-layer stack accumulative roll bonding(ARB) process. The ARB using AA1050 and AA5052 alloy sheets was performed up to 7 cycles at ambient temperature without lubrication. The specimen processed by the ARB showed a multi-layer aluminum alloy sheet in which two aluminum alloys are alternately stacked. The grain size of the specimen decreased with the number of ARB cycles, became about 350nm in diameter after 7cycles. The tensile strength increased with the number of ARB cycles, after 6c it reached 281MPa which is about twice higher than that of the starting material. The microstructures and mechanical properties of a three-layer AA1050/AA5052 alloy fabricated by the ARB were compared to those of the conventional ARB-processed material.

“…However, compared with single material rolling, there exist more difficulties in rolling bimetallic slab consisting of two different material layers [5]. Because of the different flow stresses, asymmetric deformation may occur and result in warping during flat rolling [6][7][8][9][10][11].…”

The mismatch of lengthwise elongation due to the difference of deformation resistances between constituent materials of bimetallic slab can cause warping. As the warping of bimetallic slab can lead to poor product shape with reduced productivity, this study focuses on the effect of differential speed rolling on the reduction of warping. The effects of differential speed rolling on the reduction of curvature are mainly performed by FEM based on fundamental processing parameters. Differential speed rolling experiments by using low-weight Al1050/Al6061 bimetallic slab produced by continuous clad casting have also been performed for the validation purpose. As rolling experiments for numerous processing conditions are hard to achieve, limited number of experiments has been performed in this study. Simulation results based on parametric study provide a broad overview on the warping behavior in Al1050/Al6061 bimetallic slab rolling.

“…[2][3][4] Roll bonding focuses energy between two rollers onto the point of contact between two metal sheets; the applied force, rolling temperature and rolling speed are three important parameters for roll bonding, because they can determine the pressure, time and temperature on the point of joining. [5][6][7] Roll bonding can firstly promote mechanical type of interconnection by forcing softer metal to deform then flow into the cavity gap of the harder metal, subsequently, the mounting pressure and heat generated by friction and deformation can promote forming of metallic bond between the two metals. Finally, the post-processing involves heat treating the clad metal to promote inter-diffusion between the two metal sheets to reduce defect and improved bonding strength.…”

Uninterrupted Production of Metal Coils by Making Successive Joints with Roll Bonding Technique

et al. 2009

The aim is to develop an uninterrupted processing route to manufacture metal coils, so that the efficiency of production, as well as the quality of the product and the cost-efficiency can be improved. The traditional method of joining two metal sheets is by welding; however the welding process itself can easily introduce additional processing steps and pile up the cost of production. In the past, joining two metal sheets with identical composition by the rolling process has not been easy. The present study induces dissimilarity between two sheets, i.e. pre-heat treatment for one plate to result grain growth. Experimental results indicate that such introduction of dissimilarity between two metal parts can significantly improve the roll bonding process, not only making the joint much stronger than the traditional welding technique, this newly developed method can enhance the efficiency of the production of metal coils in industries.
