“…The interfacial layer is composed of a 3 ± 1 μm thick Al12Mg17 layer next to magnesium and a 4 ± 3 μm thick Al3Mg2 layer next to aluminum. The existence and position of both intermetallic layers at the Al-Mg interface observed here are in accordance with previous studies [81][82][83][84][85]. A further increase of temperature to 673 K smoothens the interface and enlarges the widths of the intermetallic layers to 5 ± 1 μm thick Al12Mg17 and 14 ± 1 μm thick Al3Mg2.…”

Lightweight metal matrix composites are synthesized from elemental powder mixtures of aluminum and magnesium using pressure-assisted reactive sintering. The effect of the reaction between aluminum and magnesium on the microstructure and mechanical properties of the composites due to the formation of β-Al3Mg2 and γ-Al12Mg17 intermetallics is investigated. The formation of the intermetallic compounds progressively consumes aluminum and magnesium and induces strengthening of the composites: the yield and compressive strengths increase with the increase of the content of intermetallic reinforcement at the expense of the plastic deformation. The yield strength of the composites follows the iso-stress model when the data are plotted as a function of the intermetallic content.

“…Metal composite plates which consist of two or more dissimilar metallic alloys is a vital type of multilayered structures. Comparing with monolayer plates, the metal composite plates possess special capabilities such as corrosionresistance, high mechanical and thermal properties, et al From now on, the fabrication of metal composites has been carried out through numerous kinds of processes such as EXW [6][7][8][9] , diffusion bonding 10,11 , fusion welding 12 , resistance seam cladding 13 and roll bonding [14][15][16][17] . Due to considerable advantages such as high bond strength, EXW is becoming an increasingly popular method of joining.…”

“…These structures enable combinations of selective properties such as good formability, high strength and good corrosion from the constituent metallic alloys. Comparing with many metallic alloys that can act as cladding materials, like copper 21 , titanium 22 and stainless steel 17 , lightweight aluminum alloys with good corrosion resistance have been widely taken into consideration 23,24 . In this regard, the EXW process could fabricate Al/Mg composites with the advantage of combination of corrosion-resistance and high specific strength.…”

In this study, three-ply Al/Mg/Al composite plates were successfully achieved by vertical explosive welding (EXW) method. After EXW, the sound joints were obtained. Then thin three-ply Al/Mg/Al EXWed composite plates with the thickness of 1.78 mm were achieved by hot rolling. The influence of annealing on the interface microstructures and mechanical properties of the thin composite plates was investigated. The results indicated that different morphology with big waveform and mini waveform was present in the explosively bonded interface. The interface shear strength was 91MPa for big waveform side and 92Mpa for mini waveform side. The rolled sample without annealing possessed the high ultimate tensile strength (UTS) value of 235Mpa and elongation of 8.5%. The equiaxed and homogeneous grain morphology of magnesium alloys in the thin three-ply Al/Mg/Al composite plates could be induced by annealing 300°C for 1 h. This contributed to the considerable increase of elongation by 18.5%.

“…Mg alloys have relatively lower plastic deformation capacity than Al alloys, and such mismatch leads to a localized high shear stress along the interface during tensile testing. Intermetallics at the Mg/Al interface and delamination of Mg/Al laminates indicate the crack initiation from the intermetallics leads to a quick propagation along the Mg/Al interface or in the interior of intermetallics before the laminates show strain hardening effect, resulting in the low ultimate tensile stress (UTS) and elongation (EL) for samples annealed at 350 • C. In Lee's research [50], interface delamination was reported to originate in the Mg 2 Al 3 layer. Macwan [41] pointed out that cracks generally occur at the interface between Mg 2 Al 3 and Fe-containing Mg 2 Al 3 layer close to the Al side in the rolled Al/Mg/Al tri-layer laminated composite, corresponding to the observation in the present research.…”

In this paper, Mg/Al laminated composites were successfully prepared at 400 °C by corrugated + flat rolling (CFR) with reduction ratios of 35% and 25% and subsequent annealing treatments were conducted at 200–350 °C for 30 min. A two-dimensional model was established to analyze the strain distribution during the first corrugated rolling process. Simulation results indicated that severe plastic deformation was formed at trough positions, which included more numerous refined grains than in the peak positions. The interfacial microstructure and mechanical property of the flattened composites along the rolling direction (RD) and the transverse direction (TD) were investigated. The results revealed that longitudinal discontinuous and transverse continuous interfacial intermetallic compounds (IMCs) were observed of the flattened as-rolled sample. Spatial distribution was provided for the grain microstructure along the thickness and rolling direction for AZ31B magnesium alloys of the CFR as-rolled composite. Mechanical property results showed that the longitudinal ultimate tensile strength (UTS) and elongation (EL) of the as-rolled sample reached 255 MPa and 4.14%, respectively. The as-rolled UTS along TD reached 325 MPa, about 30% higher than that along the RD. After heat treatment, the anisotropy of mechanical properties remained. The microstructure evolution and mechanical properties were discussed in detail.
