“…These methods enable researchers to observe, identify, and analyze various phases, grain structures, and the IMCs distribution at the interface. The use of Electron Backscatter Diffraction (EBSD) [20], [37], [43] is getting more attention from researchers nowadays because of the ability of EBSD to analyze the shape and size of the microstructure more accurately. The EBSD results were primarily examined using the phase distribution mode, which enabled the precise measurement of the intermetallic layer thickness.…”

“…The IMC layer forms a series of distinct phases, the most common being FeAl3, Fe2Al5, and Fe4Al13, depending on the speci c welding conditions and alloy compositions. P. Xu et al (2022, 2023) [37], [43], in two studies using EBSD (Electron Backscatter Diffraction), found that the dominant IMC layer is Fe2Al5. After the solidi cation process happens, then the phases transform into needle-like Fe4Al13.…”

Dissimilar metal joints, particularly those involving aluminum and iron (Al-Fe), are widely employed in engineering due to their exceptional mechanical properties and unique microstructures. The purpose of this literature review is to assess the extent and depth of research related to dissimilar metal joint research, with a specific focus on microstructure analysis and the reported findings. The review identified three key themes for improving the quality of these joints: welding techniques, parametric optimization, and material treatment. Three themes were identified, namely, the welding techniques (i.e., Friction Stir Welding, TIG-MIG Hybrid welding, etc.), parameter optimization (e.g., Taguchi method, Response Surface Method etc., and Material Treatment) and the material treatment (pre-heating, Backing Plate). This comprehensive review highlights the importance of microstructural analysis in Dissimilar Metal Joint research, providing a foundation for understanding the nuances of different welding methods and their effects on joint quality. Additionally, strategies to mitigate the challenges posed by thick Fe2Al5 formation are discussed, ultimately contributing to advancements in dissimilar material joint technology and joint strength enhancement.

“…There are various methods suitable for joining these materials, e.g., cold metal transfer [4], by which Al is fused with a zinc layer on St by low heat input. This process produces fewer intermetallic compounds (IMCs) than fusion welding because the heat input is lower [5]. Mechanical joining methods are also used to join Al to St, such as direct pin pressing [6], by which no IMC is formed.…”

The development of new joint configurations suitable for dissimilar materials enables a wider range of applications and allows for an accelerated replacement of traditional structural construction materials by lightweight materials. The T-configuration is a joint configuration that has not been sufficiently studied for use with dissimilar materials, especially when created using the friction stir welding (FSW) process. In this study, a combined lap/butt design was introduced and implemented, seeking to create a T-joint between aluminum and steel. Characterization of the joints showed that FSW could be successfully used to join aluminum and steel in a T-configuration. The formation of intermetallic bonds and kissing bonds was carefully analyzed, and their contribution to the fracture behavior during loading in the skin and stringer directions was studied. Finite element simulation was used to determine the stress state at the interface during loading. The characterization results showed that the intermetallic, as an indicator of metallurgical bonding, is formed when special features are observed in the pattern of material flow. The fractography images showed that the stress state has a major impact on the fracture. The results of the present study can be effectively used to design and fabricate dissimilar joints, taking into account the loading condition.
