“…It consists in surface joining of elements, such as plates [5][6], tubes [7] or bars [8][9] made of different metals [5][6][7][8][9][10][11][12][13]. Its growing popularity this method owes to the fact that it is uncomplicated and relative cheap, while modern variants of explosives are characterized by high safety during their manufacture and use.…”

“…In addition, the explosive welding method enables round bimetallic semi-finished products to be obtained, which are characterized by a circular cross-section symmetry and very good joint quality. The explosive welding method is one o the few methods enabling Mg/Al stock to be produced, which is characterized by high bond strength of the bond region [8,15].…”

The paper has presented the results of theoretical studies and experimental tests of the plastic deformation of Mg/Al bimetallic specimens. Theoretical studies were carried out using the Forge2011® computer program. Physical modeling, on the other hand, was performed using the Gleeble3800 simulator. Bimetallic bars of an outer diameter of 22.5 mm and a cladding layer thickness of 1.7 mm were obtained by the explosive welding method. Samples for formability tests, characterized by a diameter-to-length ratio of 1, were taken from the bars. The theoretical studies and experimental tests were carried out for the temperature range from 300 to 400°C and for different strain rates. Based on the obtained investigation results it has been found that the main parameters influencing the formability of Mg/Al bimetallic bars are strain rate than the process temperature.

“…Successful research on the joining of Mg with Al as well as the fabrication of Mg-Al compound parts is expected to further increase the application of these materials in lightweight structures. Different methods have been used to join these two types of materials, for instance, MIG welding [1], laser welding [2], friction stir welding [3], diffusion bonding [4,5], hot rolling [6,7], explosive cladding [8], twin-roll casting [9].…”

This paper discusses the joining of AZ91 magnesium alloy with AlSi17 aluminium alloy by compound casting. Molten AZ91 was cast at 650 o C onto a solid AlSi17 insert placed in a steel mould under normal atmospheric conditions. Before casting, the mould with the insert inside was heated up to about 370 o C. The bonding zone forming between the two alloys because of diffusion had a multiphase structure and a thickness of about 200 µm. The microstructure and composition of the bonding zone were analysed using optical microscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy. The results indicate that the bonding zone adjacent to the AlSi17 alloy was composed of an Al3Mg2 intermetallic phase with not fully consumed primary Si particles, surrounded by a rim of an Mg2Si intermetallic phase and fine Mg2Si particles. The bonding zone near the AZ91 alloy was composed of a eutectic (an Mg17Al12 intermetallic phase and a solid solution of Al and Si in Mg). It was also found that the compound casting process slightly affected the AZ91alloy microstructure; a thin layer adjacent to the bonding zone of the alloy was enriched with aluminium.

“…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.
