“…In a recent study it was shown that an additional 5 turns will provide exceptional hardness in the hybrid Al-Mg system by HPT due to the combination of further grain refinement, solution strengthening, and precipitation hardening. 30 It should be noted that there are at present some limited reports of the production of Al/Mg/Al layered sheets which demonstrate the formation of intermetallic compounds by hot or warm rolling and ARB processing [23][24][25]45 but there are no reports of either a nanostructured matrix phase or nano-scale intermetallic phases.…”

“…[21][22][23][24][25] This approach was also developed using the accumulative roll bonding (ARB) process 26 but the essential drawback of the processed metal plate after ARB involves the anisotropic mechanical response which is dependent upon the rolling direction and the through-thickness direction. 27 A very recent report demonstrated a solid-state reaction in an Al-Cu system through the bonding of semicircular halfdisks of Al and Cu through HPT at ambient temperature for up to 100 turns 28 and the vision of architecturing hybrid metals through HPT was discussed using computational calculations.…”

Disks of commercial Al-1050 and ZK60A alloys were stacked together and then processed by conventional high-pressure torsion (HPT) through 1 and 5 turns at room temperature to investigate the synthesis of an Al-Mg alloy system. Measurements of microhardness and observations of the microstructures and local compositions after processing through 5 turns revealed the formation of an ultrafine multi-layered structure in the central region of the disk but with an intermetallic b-Al 3 Mg 2 phase in the form of nano-layers in the nanostructured Al matrix near the edge of the disk. The activation energy for diffusion bonding of the Al and Mg phases was estimated and it is shown that this value is low and consistent with surface diffusion due to the very high density of vacancy-type defects introduced by HPT processing. The results demonstrate a significant potential for making use of HPT processing in the preparation of new alloy systems.

“…The compression parameters, i.e. temperature, deformation and strain rate, were selected based on references [18][19][20]27], where the Al-Mg-Al multi-layer material rolling process was investigated. The compression tests were conducted for the following parameters: temperature -420ºC, strain rate -0.…”

“…Depending on the employed fabrication process and its parameters, the microstructure of the resulted coating may be composed of two continuous layers of intermetallic phases: the outer layer-Al 3 Mg 2 and the inner layer-Mg 17 Al 12, or may have an eutectic structure of (Mg 17 Al 12, phase + solid solution of Al in Mg). There are also a lot of studies concerning the fabrication of Al-Mg bimetallic or Al-Mg-Al multi-layer products by hot-pressing [13,14], extrusion [15][16][17], hotrolling [18][19][20], cold-rolling [21] explosive cladding [22], twin-roll casting [23], in which the outer layer is either of pure aluminium or an aluminium alloy and can provide anticorrosive protection. During fabrication of Al-Mg bimetallic W pracy przedstawiono wyniki modelowania fizycznego odkształcania materiału dwuwarstwowego AZ31/eutektyka z wykorzystaniem symulatora procesów metalurgicznych Gleeble 3800.…”

The eutectic layer was produced on the Az31 substrate using thermochemical treatment. The specimens of Az31 alloy were heat treated in contact with aluminium powder at 445°C in a vacuum furnace. Depending on the heating time, Al-enriched surface layers with a thickness of 400, 700 and 1100 µm were fabricated on a substrate which was characterized by an eutectic structure composed of the Mg17Al12 phase and a solid solution of aluminium in magnesium. In the study, physical simulation of the fabricated two-layered specimens with a varying thickness of the eutectic layer were deformed using the plane strain compression test at various values of strain rates. The testing results have revealed that it is possible to deform the two-layered Az31/eutectic material at low strain rates and small deformation values.

“…It therefore seems justifiable to protect magnesium with aluminium coatings using methods that ensure an outer layer with the adequate thickness and bond quality to be obtained. Layers of this type are possible to be obtained using metal forming processes, such as extrusion [18][19][20], hot-rolling [21][22][23], coldrolling [24], explosive cladding [25], twin-roll casting [26] and ARB (Accumulative Roll Bonding) [21].…”

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.
