“…Several methods of joining steel to Al have already been investigated, involving solid state joining, [1][2][3][4][5] reactive wetting (interaction between solid steel and liquid Al) [6][7][8][9][10][11][12][13][14][15][16][17][18] or laser key hole welding. 19,20 The steel to Al solid state joining was studied using various processes, such as explosion welding, 1 friction welding, 2,3 and more recently friction stir welding. 4,5 Classical welding processes such as arc welding, 6,7 resistance spot welding 8,9 and brazing 10 were used to develop a solid steel to liquid Al joining.…”

The joining of DC04 steel to 6016-T4 Al alloy is achieved by laser braze welding using a 4047 (Al12Si) filler wire and a brazing flux. The dissimilar joining is obtained both by welding the parent 6016 alloy to the 4047 filler wire, producing a continuous bonding without apparent macroscopic flaws, and by reactive wetting of the molten Al alloy on the solid steel, resulting in the formation of a thin layer of Fe-Al-Si intermetallic compounds at the steel/bead interface. The linear strength of the assemblies can be as high as 190 N mm 21 , with a failure generally located in the reaction layer of the steel/bead interface. Last, the strength of the assemblies is shown to increase linearly with the reaction layer width.

“…In dissimilar systems such continuity is guaranteed due to the presence of an IMC layer, but when the layer thickness grows, the welded system becomes brittle [75]. Kaway et al [50] besides having similar results for tensile strength, also indicates that a homogeneous layer of IMC with a thickness of 0.2 mm guarantees the bonding arguing that low thicknesses increases the strength of the joint.…”

“…While authors like Aritoshi & Okita [48], and Muralimohan et al [49] remark the exclusive formation of Fe2Al5, on the other hand Seli et al [39] argue the presence of FeAl3. Otherwise, Fukumoto et al [17] reports the formation of both IMC, likewise Kawai et al [50] describe the presence of IMC, but without specify its nature.…”

Weldability of aluminum-steel joints has been studied mainly to avoid the formation of IMC. Nowadays, there are two ways to control the effect of FexAly in welding: 1) the elimination of IMCs or 2) the generation of a thin and homogeneous layer of these phases. In this way, the present work explores the first route, manufacturing joints aluminum-steel using solid state welding process. In order to evaluate the effect of the welding parameters, temperature measures were carried out during the process as well as the microstructural evaluation using optical microscopy and SEM. Finally, the welded joints were subject to tensile strength tests to evaluate their mechanical behavior and try to stablish the nature of the interfacial bonding between both metals. The microstructural characterization of the joints does not reveal the formation of IMCs; this is attributed to the low temperature reached during the process, lower than 545 °C. The welded joint failures in the TMAZ, in the low hardness zone, product of the over aging of the precipitates β". The nature of the bonding in the interface is not clear yet, but it is considered that the atomic diffusion trough the interface and adhesive bonding favors the joint.

“…Several attempts have been made to increase the strength of the friction welding joint between aluminum and steel, especially in the variation of friction welding parameters such as initial friction, forging stage, friction time and rotation speed. Kawai et al [13] have performed friction welding on solid shafts of various aluminum alloys and low carbon steels with various presses and presses of forgings as well as 3000 rpm rotational speed with flat specimens without chamfer. They found that the higher the upset pressure and the shorter the friction time, the higher the strength of the weld joints for Aluminum A6061 and S25C carbon steel.…”

This paper reports the torsion strength of dissimilar metals friction welded aluminum alloys A6061 and mild steel St41 round bar affected by various one-sided chamfer angle and burn-off length. In this study, cylinder specimens were made of aluminum alloy A6061 and mild steel St41. On the contact area of stationary specimens, chamfer angle of 30, 45, 60, and 90 degrees or no chamfer with chamfer length of 5 mm and 18 mm diameter were machined. Continuous drive friction welding was performed with the revolution speed of 1600 rpm, initial compressive force of 7 kN, and burn-off the length of 10, 15, and 20 mm, then upset compressive force of 14 kN was applied on the specimen for 40 seconds. Torsion strength of the specimens was conducted based on the ASTM standard. Macrostructure observation and microhardness testing were also done on the friction weld joint. From the results, it was found that maximum torsion strength occurred in the specimen of dissimilar metal A6061 & mild steel St41 friction weld with chamfer angle of 30 degrees and burn-off length of 15 mm and fractured in aluminum alloy part. It may occur due to the complete cone geometry, minimum porosity, and adequate total burn-off length in the specimen.
