“…FSW is a type of solid-state welding, and it is also an eco-friendly and economical welding process. 88,89 Friction between the rotating shoulder and the workpiece heats the material and softens the workpiece. Then, bonding happens by mixing plasticized material from leading edge to trailing edge due to the rotating pin's stirring action and transverse movement of the tool along the weld line.…”

The demand for higher fuel efficiency and low fuel pollution rates leads to the development of lightweight hybrid structures. The predominant aim is to develop innovative light products with extreme versatility with bionomic and economic balance. Lightweight materials in the structures have successfully solved these problems in many industries, especially automobiles and aerospace. There is an emerging scope in producing automotive components by joining Al and Mg-based alloys with materials such as thermoplastics, ceramics and fibre-reinforced composites. Developing hybrid structures by employing metal–polymer joining is still a significant challenge. There are as many joining techniques available for joining metal with a polymer. Owing to certain drawbacks, some methods are ineffective, such as high processing time for adhesive bonding and mechanical fastening due to increased weight. The friction-based welding technique benefits hybrid joining due to its low heat-affected zone with less metallurgical damages. The study provides an overview of many emerging technologies for joining aluminium to thermoplastic/carbon fibre-reinforced polymer for lightweight structures. The paper compares different joint configurations and the effect of process variables on the microstructural and mechanical properties of hybrid joints. In addition, attempts are made to comprehend contemporary developments in the finite element simulation studies of hybrid structures. The paper also highlights recently developed strategies and gaps in areas where future studies might be focussed. Thus, the paper gives an overview of the advancements and relevance of the emerging joining technique for aluminium to polymers/carbon fibre-reinforced polymer hybrid structures.

“…Heat is generated by the friction between the rotating tool and the plate material, while pressure is applied, resulting in a plasticized zone formed around the probe. The tool moves, and stirs the plasticized area, frictionally heating and plasticizing new material along the joint line [6]. Being a generally melt-free technique, friction stir welding can enable a better control over the grain size.…”

In the motorsport industry, the choice of material for manufacturing the heat resistant components often falls on titanium alloys. In most cases, the production flow for this kind of part involves CNC machining and subsequent assembly by welding process, to other parts obtained by cold plastic forming and possibly made using different titanium alloys. Hence, the alloying element-content in the joint area can be extremely heterogeneous and variable point-by-point. To investigate this topic further, dissimilar welding of the alpha/beta alloy Ti6Al4V and of the oxidation-resistant alpha alloy KS-Ti 1.2 ASN-EX was made by GTAW technology and using different filler metals. Chemical and mechanical properties of the welds were investigated by XRD, SEM-EDS, microhardness maps, and tensile and bending tests. Results show that, despite the different alloying elements present in the two filler wires investigated, static properties of the welds are similar. Results also show that the local V/Al content ratio affects the microhardness as it is responsible for the creation of supersaturated alpha phases during the cooling of the weld beads.

Metal–polymer hybrid structures are becoming desirable due to their wide range of applications in the automotive, aerospace, biomedical and construction industries. Properties such as a light weight, high specific strength, and design flexibility along with the low manufacturing costs of metal–polymer hybrid structures make them widely attractive in several applications. One of the main challenges that hinders the widespread utilization of metal–polymer hybrid structures is the challenging dissimilar joining of metals to polymers. Friction stir welding (FSW) shows a promising potential in overcoming most of the issues and limitations faced in the conventional joining methods of such structures. Several works in the literature have explored the FSW of different metal-to-polymer combinations. In some of the works, the joints are examined based on processing parameter optimization, microstructural characteristics, and mechanical performances. It is, therefore, important to summarize the findings of these works as a means of providing a reference to researchers to facilitate further research on the utilization of FSW in joining metals to polymers. Thus, this work aims to present a comprehensive technical review on the FSW technique for joining metals to polymers by reviewing the reported literature findings on the impact of materials, tools, process parameters, and defects on the strength and microstructure of the produced joints. In addition, this work reviews and presents the latest practices aiming to enhance the metal–polymer joint quality that have been reported in the literature.
