“…So wide and cross applications of these two metals make the connection of Mg/Al dissimilar metals inevitable [3]. For example, the Mg-Al laminated armor is used in tanks and armored vehicles [4], Mg/Al complex structure is used in aerospace engines and components [5,6,7]. So it is significant to achieve reliable connection of Mg/Al dissimilar metals.…”

Abstract. In this study, Finite elements method (FEM) was used for simulations on the annealing treatment. And the distributions of residual stress were obtained from the resualts of simulitions. Besides, in order to study the mechanical properties. Composite plates of AZ31B magnesium alloys and 6061 aluminum alloys were fabricated by vacuum diffusion bonding method. Then experiments about annealing, measurement of residual stresses and tension test were also carried out. The results of residual stresses obtained by X-ray diffraction (XRD) were compared with the results of simulations. It can be thought that the results of residual stress obtained from simulations and that from experiments are in a good agreement. What's more, The residual stress after annealing at 250℃ is the least of all, while the tensile strength is the strongest. On the basis of results of simulations and experiments, the conclusion can be obtained that 250℃ is the most appropriate annealing temperature.

“…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.…”

AnAlysIs of the deformAbIlIty of two-lAyer mAterIAls AZ31/eutectIcAnAlizA możliwości odksztAłcAniA plAstycznego mAteriAłu dwuwArstwowego Az31/eutektykAThe paper present the results of physical simulation of the deformation of the two-layered Az31/eutectic material using the Gleeble 3800 metallurgical processes simulator. 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.

“…However, magnesium has a hexagonal crystal structure with few slip systems and poor plastic deformation capacity, making it difficult to manufacture into sheets, strips or other types [3]. In addition, magnesium is reactive with air by forming magnesium oxide, which leads to a low corrosion resistance [4]. A lot of researches were conducted on this important topic.…”

In this study, Al-Mg-Al trilaminated thin plates were fabricated by one-pass hot rolling to improve the processing capacity and bonding strength of magnesium alloy plates. The effects of processing parameters were investigated. The results show that the optimal bonding strength is up to 20 MPa with a reduction ratio of 40 % and rolling temperature of 400°C, superior than that in other one-pass rolling studies with regard to thin laminated plates. In addition, a favorable property is achieved with the annealing temperature of 250-300°C or annealing time of 1.5 h. When the annealing temperature exceeds 300°C or annealing time exceeds 1.5 h, respectively, the bonding strength of Al/Mg/Al plate decreases. The scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) analyses suggest that the appearance of thin diffusion layers between Al and Mg interfaces is helpful to improve the bonding strength, while the presence of thick diffusion layer would reduce the bonding strength greatly.
