“…the AJ62/AlSi17Cu4Mg engine block fabricated by die casting [1]. Mg/Al composites have been fabricated by friction stir welding [2], twin roll casting [3], roll cladding [4], co-extrusion [5], accumulative roll bonding (ARB) [6] and high pressure torsion (HPT) [7,8]. Amongst the Mg/Al composites fabricated through these techniques, a substantial variation in bonding quality and intermetallics formed at the interface is found.…”

“…Furthermore, different materials can easily be combined to produce laminated structures, which are denoted as laminated metal composites (LMCs) according to Lesuer et al [5]. Many studies have been carried out on this area with different materials: Al/Cu [6], Al/Mg [7], Fe/Cu [8], and some others. Due to the excellent results on ARB-processed aluminum mono-material sheets also many Al/Al LMCs have been fabricated (e.g., [9,10]).…”

Laminated metal composites (LMCs) with alternating layers of commercial pure aluminum AA1050A and aluminum alloy AA5005 were produced by accumulative roll-bonding (ARB). In order to vary the layer thickness and the number of layer interfaces, different numbers of ARB cycles (4, 8, 10, 12, 14 and 16) were performed. The microstructure and mechanical properties were characterized in detail. Up to 8 ARB cycles, the ultrafine-grained (UFG) microstructure of the layers in the LMC evolves almost equally to those in AA1050A and AA5005 mono-material sheets. However, the grain size in the composites tends to have smaller values. Nevertheless, the local mechanical properties of the individual layers in the LMCs are very similar to those of the mono-material sheets, and the macroscopic static mechanical properties of the LMCs can be calculated as the mean value of the mono-material sheets applying a linear rule of mixture. In contrast, for more than 12 ARB cycles, a homogenous microstructure was obtained where the individual layers within the composite cannot be visually separated any longer; thus, the hardness is at one constant and a high level across the whole sheet thickness. This results also in a significant higher strength in tensile testing. It was revealed that, with decreasing layer thickness, the layer interfaces become more and more dominating.

“…So prepared packages were heated up to a temperature 420°C in a chamber furnace, and then put through the rolling process. The rolling temperature was chosen based on the analysis of the investigation results reported in studies [37,38], which showed that the quality of bond in Al-Mg-Al multi-layer materials rolled by the ARB method depended on the rolled material temperature. The investigation showed that a high-strength bond in Al-MgAl materials was possible to be obtained at a temperature of 400°C.…”

The paper presents the results of the experimental study of the three-layer Al-Mg-Al sheets rolling process by the ARB method. The tests carried out were limited to single-pass symmetric and asymmetric rolling processes. An Al-Mg-Al package with an initial thickness of 4 mm (1-2-1 mm) was subjected to the process of rolling with a relative reduction of 50%. To activate the shear band in the strip being deformed, an asymmetry factor of av=2 was applied. From the test results, an increase in the tensile strength of the multi-layer Al-Mg-Al sheets obtained from the asymmetric process was observed. Microhardness tests did not show any significant differences in aluminium layer between respective layers of sheets obtained from the symmetric and the asymmetric process. By contrast, for the magnesium layer, an increase in microhardness from 72 HV to 79 HV could be observed for the asymmetric rolling. The analysis of the produced Al-Mg-Al sheets shows that the good bond between individual layers and grain refinement in the magnesium layer contributed to the obtaining of higher mechanical properties in the multi-layer sheets produced in the asymmetric process compared to the sheets obtained from the symmetric process.
