“…In the last stage of their work, the nano-sized SiC particle was reinforced by considering the optimal values obtained from previous stages. The tensile properties for the specimen reinforced with the nano-SiC particles were the 32,81 highest (UTS = 237.77 ± 10 MPa and YS = 176.67 ± 10 MPa) of all other welded specimens, which are attributed to the pinning effect. Also, the highest toughness and higher hardness were recorded for the samples incorporated with the nano-SiC particles.…”

“…The grain refinement in the SZ is due to the dynamic recrystallization (DRX) that transformed stretched microstructure into equiaxed grains. 32,[111][112][113] The addition of reinforcing particles exhibited even finer grain structures due to the effect of reinforcing particles themselves and DRX from the FSW process. 34 Moreover, the particles interact with matrix material and increase the nucleation sites by breaking the initial grains that restrain the grain boundary movement.…”

“…Also, the threaded cylindrical tools may show more microhardness than other cylindrical tools due to their grooved design, resulting in intense forging on the base material. 32 Abdollahzadeh et al 131 analyzed the effect of SiC particles on the hardness of a composite joint produced by the FSW process. They observed higher hardness in the SiC-reinforced specimen than that of an unreinforced specimen which depicts that the reinforcement of particles plays a vital role in increasing the hardness of the welded specimen.…”

Friction stir welding is a solid-state environment-friendly joining process with many advantages over all fusion welding processes. Many variants in friction stir welding are used for uplifting the process to its maximum possible extent. One such variant is particle reinforcement in the weldment, which is used for improving the mechanical properties by enhancing the metallurgical aspects in the weld region. Generally, micro- and nano-sized ceramic particles are used for reinforcing, which have a much higher melting point than the materials to be joined. From the literature studies, particle size plays a prominent role in attaining better mechanical properties in reinforcing techniques. In addition, an increase in particle size decreases the corresponding mechanical property. Higher heat input conditions like higher tool rotational speed and low welding speed are preferred as they better mix reinforced particles with the matrix material in the weld zone. However, the higher input conditions in the regular friction stir welding process coarsen the grains, thereby deteriorating the mechanical properties of the joint. Increasing the number of passes and switching the direction between the passes leads to uniform distribution of particles and enhance the mechanical properties. This review article's main aim is to understand better reinforcement particles in the weld line of a friction stir welding process. Also, the author emphasizes reinforcing the combination of nano and microparticles to reduce the cost of reinforcement without compromising the mechanical properties. The work mentioned above is missing in the open literature.

This manuscript proposes an enhanced technique for the friction stir welding (FSW) of ceramic particle‐reinforced aluminium‐related metal matrix composites. The proposed technique is the joint implementation of both the Aquila Optimizer and Pelican Optimization Algorithm. This proposed method aims is to enhance the welding efficiency, quality, and overall performance of the weld joints. The test is conducted in an all‐purpose machine at cutting speeds that permit temperatures that are comparable to the FSW of stainless‐steel, aluminium alloys and copper. Reaction–diffusion studies are conducted to better understand the diffusion‐control process under tool wear, and the tool wear rate is determined by the length of the cutting tool's nose tip. Rotational speed at 10 mm/min is examined. SiC exhibits the highest performance of aluminium and stainless steel. As the fraction of SiC increases to 18%, the axial force and rotational speed of FSW also increase.

In this study, friction stir spot welded joints of Al6061-T6 were obtained using Silicon Carbide particles as reinforcement. The effect of reinforced particles along with process parameters was analyzed in terms of tensile-shear strength, weld structure, hook formation. The investigations revealed that tensile-shear strength increased by 29.78 % with incorporation of silicon carbides particles in the weld region. The guiding hole diameter was found to be signi cant parameter for improved weld strength. Combination of moderate tool rotation speed, higher pre-dwelling time and guiding hole diameter were recognized as effective combination of process parameters. Weld cross sections were studied under stereo zoom microscope and optical microscope to observe different bonding regions. The scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) con rmed the presence of silicon carbides particles in weld region.
