“…Metallurgically, such LMCs pose less of a challenge at their interface with iron and its alloys than do aluminium alloys: Refs. [17,22,23] give examples of interfacial engineering in magnesium-steel LMCs produced by reactive transient liquid phase bonding, or by pressure infiltration, respectively. On the other hand the wet corrosion resistance of this LMC is dismal: to be usable it must be completely sealed from the environment with a protective coating.…”

This contribution draws practical implications of a recently published estimation of the tensile ductility in laminated composites made of two ductile materials, typically metals or alloys, which harden as both the strain and the strain-rate increase. To this end, the literature is surveyed to collect values for the strain hardening exponent, the strain-rate sensitivity and the strength constant for a wide range of engineering metals and alloys. Material combinations that might produce ductile laminated metal composites are then examined in light of the data and theory. A simple graph is proposed, which gives a direct reading of the predicted elongation to failure of composites containing equal volume fractions of any two materials among those surveyed. The resulting plots show material combinations in which a more ductile material can significantly increase, within a Laminated Metal Composite (LMC), the tensile elongation of a less ductile material. In this role, 304 stainless steel and commercial purity iron emerge as sensible possibilities.

“…The bondability of AZ31 to low carbon steel with the addition of Ag interlayer using rTPL process showed that isothermal solidification of the eutectic melt was formed at the Mg alloy side through the diffusion of Ag into the magnesium BM. Thin and uniform Fe 2 Al 5 layer was observed at the steel side, which significantly improved the joint strength to 201 MPa [44,81]. In contrast, coarse, non-uniform IMC intermittently formed at the interface without Ag interlayer, which deteriorates the joint performance.…”

“…The number of research suggested that interfacial bonding could be achieved by either addition of interlayer or some alloying elements in the Mg BM. The benefits of using Cu [78][79][80], Ni [37,80], and Ag [44,81] interlayers during diffusion bonding of Mg alloy/steel have been demonstrated.…”

“…Some authors focused on bonding magnesium alloys to steel using reactive transient liquid phase bonding (rTLP) to improve the joints strength between dissimilar metals. During the rTPL process, eutectic melting and subsequent isothermal solidification occurred between the interlayer and the magnesium, while the formation of a thin continuous layer between the melt and the steels resulted in interfacial bonding of the steel with the magnesium substrate [44,81]. The bondability of AZ31 to low carbon steel with the addition of Ag interlayer using rTPL process showed that isothermal solidification of the eutectic melt was formed at the Mg alloy side through the diffusion of Ag into the magnesium BM.…”

“…Currently, a great deal of research has been conducted on the interface characteristics and mechanical performance of Mg alloys to steel joints, particularly under static loading. Under optimized processing conditions, excellent static strength has been achieved, even surpassing that of Mg alloy base metal with insertion of Ag, Cu, and Ni intermediate elements [38,44]. However, few experiments have been carried out on the corrosion behavior of the jointed parts and the joints performance under dynamic loading [45][46][47][48].…”

Hybrid structures built using Mg/steel are expected to have an increasing impact on the future developments of the manufacturing sector, especially where lightweight structures are required in order to reduce fuel consumption, greenhouse gases and improve efficiency of energy-converting systems. To this end, there is a pressing need for a joining technology to produce effective and low-cost dissimilar Mg/steel joints. Joining of these materials has always been a challenging task for researchers, due to the wide discrepancies in physical properties and lack of metallurgical compatibilities that make the welding process difficult. Based on the existing literature, a successful joint between magnesium alloys and steel can be achieved by inserting an interlayer at the interface or mutual diffusion of alloying elements from the base metal (BM). Thus, intermetallic phases (IMCs) or solid solutions between Mg and the interlayer and also the interlayer and Fe formed at the interface. However, the interfacial bonding achieved and the joints performance depend significantly on the intermediate phase. This paper reviewed the research and progress in the area of joining of Mg alloys to various grades of steel by variety of welding processes, with focus on the techniques used to control the morphology and existence state of intermediate phase and improving the mechanical properties.
