“…Instead, it relies on high pressure and/or high heat to create a bond between the materials at the atomic level, though never exceeding the melting points of the base components [190]. The main techniques of SSW are diffusion bonding [191], friction stir welding [192][193][194][195], forge welding [196][197][198], cold welding [199][200][201], ultrasonic welding [202,203], roll welding [202,204], and explosion welding [205,206]. This technique allows for the production of strong, high-quality joints without the need for filler materials and can be used to join dissimilar metals that cannot be welded using conventional methods.…”

Microbially influenced corrosion (MIC) is a potentially critical degradation mechanism for a wide range of materials exposed to environments that contain relevant microorganisms. The likelihood and rate of MIC are affected by microbiological, chemical, and metallurgical factors; hence, the understanding of the mechanisms involved, verification of the presence of MIC, and the development of mitigation methods require a multidisciplinary approach. Much of the recent focus in MIC research has been on the microbiological and chemical aspects, with less attention given to metallurgical attributes. Here, we address this knowledge gap by providing a critical synthesis of the literature on the metallurgical aspects of MIC of carbon steel, a material frequently associated with MIC failures and widely used in construction and infrastructure globally. The article begins by introducing the process of MIC, then progresses to explore the complexities of various metallurgical factors relevant to MIC in carbon steel. These factors include chemical composition, grain size, grain boundaries, microstructural phases, inclusions, and welds, highlighting their potential influence on MIC processes. This review systematically presents key discoveries, trends, and the limitations of prior research, offering some novel insights into the impact of metallurgical factors on MIC, particularly for the benefit of those already familiar with other aspects of MIC. The article concludes with recommendations for documenting metallurgical data in MIC research. An appreciation of relevant metallurgical attributes is essential for a critical assessment of a material’s vulnerability to MIC to advance research practices and to broaden the collective knowledge in this rapidly evolving area of study.

“…Engineers has the ability to use the distinct characteristics of several materials in order to fabricate multifunctional components that were previously unachievable using single-material approaches. The provision of design flexibility facilitates the creation of complicated and tailored structures that enhance performance in certain applications, ranging from aeroplane fuselages to car frames [48]- [49]. The enhancement of fuel efficiency and the mitigation of carbon emissions are directly facilitated by the reduction in weight achieved via the utilisation of sophisticated welding techniques for different materials.…”

The aerospace and automotive sectors are now experiencing a growing need for lightweight and high-performance components. As a result, there is a significant interest in investigating new welding methods that can effectively fuse different materials. The process of welding different materials poses notable difficulties as a result of disparities in physical qualities, metallurgical attributes, and thermal expansion coefficients. The research starts by examining the rationales for employing diverse materials in various sectors, emphasising the benefits they provide in relation to decreased weight, greater fuel economy, and improved mechanical characteristics. Following this, the study explores a range of sophisticated welding techniques that have arisen in response to these issues. This paper examines several fusion welding techniques, including laser welding, electron beam welding, and friction stir welding. Each approach is discussed in detail, with a comprehensive description of its fundamental concepts. This discussion focuses on the advantages of each approach in relation to the reduction of heat-affected zones, the attainment of precise control over the welding process, and the minimization of intermetallic compound formation. The study also emphasises the use of case studies and practical instances to showcase the effective implementation of sophisticated welding techniques on dissimilar materials. The feasibility and efficiency of these approaches in combining incompatible materials, such as aluminium to steel, titanium to composites, and others, are exemplified by instances observed in the aerospace and automotive sectors.

“…They can be assembled in different mechanical methods like gluing, welding (hot or cold welding), and hybrid methods (mixed) [1]. Cold welding consists of joining similar or dissimilar metals at temperatures below the melting point and without the use of filler material [2][3][4][5][6][7]. Among the processes used for cold welding are friction stir welding [8][9][10][11], rotary friction welding [12][13][14][15], diffusion bonding [16][17][18][19], explosive welding [20][21][22][23], or ultrasonic welding [24][25][26][27], each of them having their own advantages or disadvantages.…”

Pressure welding on cogged surfaces represents a new technological variant of the cold welding. The components that are made from a material with higher plasticity (aluminium, lead etc.), having flat surfaces, are pressed on or between the harder material components (copper, brass, carbon/stainless steel, titanium, etc.) that have cogged surfaces. The main particularity of this technique is to achieve an appropriate joint by deforming only the component with higher plasticity. Due to the low degree of deformation needed, reduced pressure forces are applied in comparison with the classical cold pressure welding. The welding in isolated catching nodes is achieved by gripping, while the aluminium is gliding on the flanks of the teeth. The tensile strength of the joint is relatively low reaching up to 10% of the aluminium part, but can be improved by applying a heat treatment. Welded joints were made in various combinations, resulting in bimetallic or multilayered workpieces. Due to the negligible contact resistance, these joints can be appropriately used for applications in the electrotechnical field.
