“…Explosive welding is noted for its capability of offering high strength bonding and cladding metals that are unweldable or are difficult to weld by other methods. It has been developed as a promising way to clad dissimilar materials [5][6][7][8][9][10][11][12][13]. Thus, some attempts have been made to clad other materials on Mg alloys by explosive welding.…”

“…Thus, some attempts have been made to clad other materials on Mg alloys by explosive welding. Arisova [5] reported that aluminum was successfully coated on magnesium alloys by explosive welding and investigated the effects of heat treatment on the nature of change in micro-mechanical properties and phase composition of Mg/Al clad plate. Chen [6] joined the 1100 aluminum and AZ31 magnesium alloy using an explosive welding method and analyzed the welding parameters, including explosive thickness and stand off on the bonding surface.…”

In this paper, the microstructure and properties of a Ti/Mg alloy clad plate manufactured by explosive welding were studied. The bonding interface was inspected by ultrasonic examination (US). The microstructure and the composition of the clad were characterized by OM and SEM. Properties were inspected by tensile test, shearing test, microhardness test and electrochemical corrosion. The results showed that the bonding interface of the clad plate was made up of straight areas and wavy areas. In straight areas, element diffusion occurred across the bonding interface. Additionally, in wavy areas, a melting zone occurred in the Mg alloy layer near to the bonding interface. Lots of light particles embedded on the melting zone. Tensile test results were comparable with the Ti sheet and the ultimate tensile strength of the clad plate demonstrated an 18% increase. The shearing strength of the clad plate was about 68–87 MPa. The microhardness of the clad plate was higher than that of the original sheets from the interface to 300 μm away. At over 300 μm, the microhardness of the clad plate decreased and approached the original sheets. Compared with the straight area, the hardness of the Mg alloy layer in the wavy area close to the interface increased by 12%. Corrosion results showed that the corrosion potential (Ecorr) absolute value of the clad plate increased by 24%, and the corrosion current density (icorr) value was 4 orders of magnitude lower, compared with the Mg alloy sheet. It was clear that the corrosion resistance of the clad plate was higher than that of the Mg alloy sheet. Cladding Mg alloy and Ti by explosive welding would improve the industrial applications of magnesium materials.

“…In addition, the existence of intermetallic compounds was not observed, but the presence of a solid solution with a chemical composition changing in the direction from the weld to the base materials was found. The authors [19][20][21][22] studied the effect of annealing on the formation of intermetallic phases in the structure of Al/Mg composites produced by the EXW method. They found that heat-treatment leads to the development of the intermetallic phases: β-Mg2Al3 and γ-Mg17Al12.…”

The evolution of the microstructure of reaction regions in as-welded and annealed states was thoroughly investigated by SEM and TEM in the eleven-layered AZ31/AA1050 composite plates fabricated via a single-shot explosive welding process. With the detonation velocities used, only the first and second interface is wavy, while the others are flat. Near all interfaces, local melting and rapid solidification processes lead to the formation of reaction regions composed of phases of different chemical compositions and structures. Even though 2 equilibrium phases of γ-Mg17Al12 and β-Mg3Al2 have been found a large part of the solidified melt region consists of non-equilibrium phases that exhibit an amorphous or ultrafine-grained structure. Further heat treatment of the multilayer composite resulted in rapid nucleation and growth of the γ-Mg17Al12 and β-Mg2Al3 phases in the form of hard layers. Within the pre-existing reaction regions, the systematic transformation of phases of different chemical compositions into one β-Mg2Al3 phase was observed. It was found that using a pressure of 3 MPa is very important in preventing delamination of the clad during heating, but it is not able to block the formation of the linear cracks in the β-Mg3Al2 phase, which crucially reduces the composite formability.
