“…Moreover, the employment of real-time monitoring technology potentially connected to adaptative control systems [109], which have been successfully employed in laser welding systems, could bring more advancements to dissimilar joining applications. Lastly, thermo-mechanical and multi-physical simulations [110] are also expected to be further explored, although some models have already been developed by these means [71,[111][112][113].…”

The development of high-performance dissimilar aluminum–steel joints is necessary to promote the feasibility of multi-material design and lightweight manufacturing. However, joining aluminum to steel is a challenging task mainly due to the formation of brittle intermetallic compounds (IMC) at the joint interface. Laser welding is considered a very promising joining process for dissimilar materials, although its application in industry is still limited by the insufficient mechanical performance of the joints. The present paper aims to give a comprehensive review of relevant recent research work on laser joining of aluminum to steel, contributing to highlighting the latest achievements that could boost acceptance of laser joining of dissimilar materials by the modern industries. To this end, the most important challenges in laser joining of aluminum to steel are presented, followed by recent approaches to overcome these challenges, the state-of-art of comprehension of IMC formation and growth, and the different strategies to minimize them.

“…[ 21,22 ] Murakami et al [ 23 ] observed that the thickness of IMCs at the interface between carbon steel and pure aluminum joints increased with the decreasing welding speed and the increasing heat input. Yang et al [ 24 ] found that the uneven distribution of IMCs was due to the change of interface temperature along the thickness direction. A smaller temperature difference at the Al/steel interface could effectively improve the uniformity of the interfacial layer.…”

Wire and arc additive manufacturing (WAAM) provides a convenient solution for the integrated design and manufacturing of Al/steel structures. The multiple thermal cycles inherent in WAAM can affect the Al/steel interface and ultimately the overall performance of the Al/steel structure. Herein, the evolution behavior of the Al/steel interface microstructure under different WAAM modes, number of thermal cycles, and interpass temperature is investigated. The results show that the process of heat accumulation plays an important role in the evolution of Al/steel interface. As the number of thermal cycles increases, the intermetallic compounds layer gradually transforms from the mainly τ5‐Al8Fe2Si phase to (Al, Si)13(Fe, Cr)4 phase. The rise of interpass temperature significantly aggravates the microstructural evolution process, but the final interface structure can be manipulated employing temperature control. When the interpass temperature is lower than 250 °C, the formation of the brittle Fe2Al5 phase is avoided. With the increase of thermal cycles, the shear strength of Al/steel additive specimens increases first, then decreases, and finally tends to be stable. The changes in shear strength are closely related to the interface microstructures.
