“…The microstructure was observed to vary from the direct irradiation zone to the FZ root. The local heating characteristics of the temperature gradient along the interface were considered as the main reason for the evident variation of microstructure along the FZ/Ni interface [20,21]. coating was dissolved into the FZ during laser irradiation.…”

Joining Al alloy to steel is of great interest for application in the automotive industry. Although a vast number of studies have been conducted to join Al to steel, the joining of Al to steel is still challenging due to the formation of brittle Fe-Al intermetallic compounds. In this work, the microstructure and mechanical properties of the dissimilar Al/steel joints with and without a nickel coating are comparatively investigated. A homogenous reaction layer composed of FeZn 10 and Fe 2 Al 5 is formed at the interface in the joints without Ni coating, and the joint facture load is only 743 N. To prevent the formation of brittle Fe 2 Al 5 , Ni electroplated coating is applied onto a steel surface. It has been shown that a nonhomogeneous reaction layer is observed at the interfacial region: Ni 5 Zn 21 is formed at the direct irradiation zone, while Al 3 Ni is formed at the fusion zone root. The microhardness of the interfacial layer is reduced, which leads to the improvement of the joint mechanical properties. The average fracture load of the Al/Ni-coated steel joints reaches 930 N. In all of the cases, failure occurs at the Ni coating/fusion zone interface.

“…According to the Zn-Fe phase diagram, Zn and steel could generate intermetallics [15]. Yang J et al [16] added Zn to the fusion zone of the Al/steel joint which was achieved by laser welding. Due to the addition of the Zn, the IMC in the Al/steel joint changed from the layered Fe 2 Al 5 and needle-like FeAl 3 to M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT layered Fe 2 Al 5-x Zn x and dispersed FeZn 10 with minor Al rich amorphous phase.…”

The effect of Zn interlayer on the microstructure and mechanical properties of dissimilar A1100 and SUS316L friction stir welded (FSW) butt joints was investigated. The results showed that Zn could improve the joint's tensile strength. However, a complete dissolution of the Zn interlayer was necessary to achieve a sound joint. During the FSW process, the stirring action of the tool dispersed the Zn into the A1100 matrix forming a solid solution of Zn. A direct relationship was found between the tool rotational speed and the Zn dissolution rate. Also, the addition of Zn inhibited the Al-Fe IMCs growth, which played a positive role in the obtained tensile strength.
