“…The maximum mild tensile strength of the joint could reach 144 MPa. Wang et al [ 195–198 ] studied the effects of heat input and Al content in the weld on the mechanical properties of Q235 low‐carbon steel and AZ31B Mg alloy‐welded joints. Experiments have found that the welding heat input and the Al content of the weld have a significant effect on the strength of the steel/Mg joint.…”

Since the beginning of the 21st century, countries around the world have continuously increased their efforts in environmental governance. It has higher requirements for the performance of materials, not only to ensure that it is clean and nonpolluting, but also to maximize benefits. The mechanical properties and economic value of a single material can no longer meet the production needs of enterprises. Therefore, more people use composite materials to replace single materials. The use of composite materials not only can effectively respond to the concept of green development, but also reduces cost input to a lager extent. The composite of dissimilar metals can volatilize the respective advantages of the two materials. Common materials can be used to replace rare metals to reduce the use of precious metals. [1][2][3][4] World-renowned automobile companies such as Japan's Toyota and Honda are vigorously researching lightweight production technologies. Lightweight alloys (such as magnesium [Mg] alloys, aluminum [Al] alloys, etc.) could be used in place of steel in non-load-bearing structures. Mg alloys are one of the lightest metal materials so far, with a density of only 1.74 g cm À3 , which is about 2/3 of Al, 1/4 of zinc, and 1/5 of steel. They have high specific strength, specific stiffness, good damping performance, and easy recycling and other advantages, known as the "21st century green engineering metal materials." Titanium (Ti) alloy is expensive and its processing performance is relatively poor. Steel has

“…The notable approaches are the application of interlayer, cover plate, low heat input, combination of welding and mechanical joining, and appropriate alloying of filler metals. Table 2 presents some of the attempts taken by different researchers to enhance the performance of dissimilar metal welds of steel-aluminum , aluminum-magnesium [63][64][65][66][67][68][69] , and steel-magnesium [70][71][72][73][74][75][76][77][78][79] . In terms of present infrastructures in automotive industries, manufacturing cost, and weld quality the application of the least amount of heat input and appropriate filler metal alloys were identified as the most significant approaches.…”

This paper presents a comprehensive study of the metallurgical challenges of welding dissimilar metals. It also describes the important factors in dissimilar welding which need to be considered for automotive applications. It further investigates effective approaches to overcome these present challenges. Steels, aluminum alloys, and magnesium alloys are widely used metals in car bodies. However, it is difficult to weld these dissimilar metals and achieve good joint quality, due to their inherent disparate properties. The formation of brittle, crack sensitive and corrosion susceptible intermetallic phases is the main obstacle to dissimilar weld quality. Various approaches have been attempted by many researchers to enhance the performance of dissimilar welds. The most notable efforts include the application of interlayers, cover plate, least heat input, a combination of welding and mechanical joining, and alloying elements of filler metals. Based on considerations of joint performance, production cost and time, present industry infrastructure, and so on, the most effective and feasible approaches were identified which required the least amount of heat input, and the appropriate filler metal alloying elements.

“…The effect of Al content in Mg alloy filler wire on the microstructure and mechanical properties of the joint was also investigated. Figure 16g shows the Mg/steel joint, whose tensile strength could reach 184.2 MPa with the AZ31 filler metal added; its reaction layer was composed of FeAl IMC [54]. Joint strength could reach 192 MPa (80% AZ31 Mg alloy) with the AZ61 filler metal added [55].…”

The challenge of joining immiscible Mg/Steel dissimilar metals lies in the absence of an Fe-Mg intermetallic or Fe-Mg solid solution in an Mg-Fe system, and differences in their physical and chemical properties. Promoting interfacial reaction and regulating the composition of interface layer are beneficial for the formation of an Mg/steel interface layer and to obtain an effective Mg/steel joint. This research work focusses on the bonding of immiscible Mg/steel dissimilar metals: First, an Mg/steel interface layer was designed by controlling the composition of added alloy elements and trace elements in the base metal. Second, the Mg/steel dissimilar metals welding methods were divided into three parts—solid state welding, welding-brazing and fusion welding. The main distinctions between them were difference in interfacial temperature, thickness of interface layer, and type of compound. Third, the orientation relationships (OR) of the Mg/interface layer system and the interface layer/steel system was investigated. In this review, the effect of welding processing parameters, addition of alloy elements, base metal, and different welding methods on the joint’s performance was studied. The mechanical property, microstructure, interface layer and metallurgical reactions of the joint were also examined. The most recent progress in joining immiscible Mg/Steel dissimilar metals and future research prospects are presented at the end of the paper.
