“…Solder systems are used in many fields of industry and electronic technology all over the world for hundreds of years. After serious harmful effects of lead on human health and environment had been proven, scientists were performed considerable number of studies (Mc Cormack et al 1993, Lee et al 1997, Abtewa and Selvaduray 2000, Suganuma 2001, Doğan and Arslan 2019, Li et al 2020, Rashidi and Naffakh-Moosavy 2021 about lead-free systems. Besides, soldering research continued to be up to date because of their usage area in junctions, metal works, many parts of electronic devices etc.…”

Sn-Zn bazlı kurşunsuz alaşımlar, lehimleme için kurşun içeren alaşım sistemlerinin yerine kullanılmak üzere düşünülmektedir. Bu çalışmada, In, Ag, Al katkılı Sn-Zn esaslı sistemler üretilmiş ve en uygun sistemin elde edilmesi için mekanik ve mikro yapısal özellikler incelenmiştir. Mikro yapılar bir optik mikroskop kullanılarak gözlemlenmiştir. Numunelerin mevcut fazları Enerji Dağılım X-Işını Spektrometresi (EDX) kullanılarak araştırılmıştır. Sistemlerdeki erime sıcaklıkları, füzyon entalpisi ve sıvı ve katı fazlar arasındaki özgül ısı değişimi Diferansiyel Taramalı Kalorimetre (DSC) ile belirlenmiştir. Ayrıca oda sıcaklığında mikrosertlik değerleri de ölçülmüştür.

“…Typical methods for bonding dissimilar metals sheets includes brazing and high and low temperature solid-state welding processes, such as explosion welding and hot isostatic pressing (HIP), all of which can be used to manufacture ALA-SynRM rotors [ 11 ]. The brazing process is described as a process where the parent materials to be bonded are heated to a temperature that is lower than the melting temperature of the parent materials but higher than the melting temperature of the braze alloy [ 12 ]. As the braze alloy melts in the joint, capillary forces and the wetting action cause the braze alloy to flow throughout the joint area and, on cooling, to create a permanent bond between the workpieces.…”

High-speed electric motors, e.g., axially laminated anisotropic synchronous reluctance motors (ALA-SynRM), use a solid rotor manufactured by joining alternating layers of magnetic and non-magnetic metallic sheets. The strength of the dissimilar metallic joints is critical for the rotor’s ability to withstand the operating conditions of the high-speed electrical machine. In this work, various dissimilar metallic joint configurations that can be used in high-speed ALA-SynRM rotors are studied by analyzing the shear strength, microstructure, hardness, and composition of the joints. Metallic joints of structural steels and Inconel® alloys fabricated by vacuum brazing and hot isostatic pressing (HIP) are studied. Finite element analysis (FEA) was performed to calculate the maximum shear stress of the joints that were subjected to various high speed operating conditions. The shear strength of the test specimens was measured and compared with FEA results. The microstructure and chemical composition of the joints were studied by using optical microscopy, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) on SEM. The results show that the hot isostatic pressed S1100MC-IN718 joint achieved the highest ultimate shear strength (233.3 MPa) followed by vacuum brazed S355MC-IN600 joint (230.1 MPa) and HIP S355-IN718 (203.5 MPa), thereby showing that vacuum brazing and HIP can be viable manufacturing methods to fabricate a high-speed ALA-SynRM rotor.

“…However, EBW requires a vacuum environment, which is not necessary for LBW [23]. Brazing is a low temperature-joining process that avoids melting the base materials and is suitable for many combinations of dissimilar materials [24]. However, the strength of brazed joints is usually limited [25], hampering its use for structural applications.…”

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.
