“…Dissimilar aluminum composites are fabricated through the amalgamation of two or more distinct varieties of aluminum alloys. Various alloys can be selected to enhance the characteristics of the composite, including, but not limited to, strength, stiffness, and corrosion resistance [3][4][5]. The mechanical characteristics of dissimilar aluminum composites produced using FSW are influenced by many parameters: the selection of aluminum alloys, the manipulation of processing parameters (e.g., tool rotation speed, welding speed, and plunge depth), and the characterization of the resulting microstructure in the composite material [6][7][8][9].…”

In the present study, AA7075 and AA2024 aluminum alloys were reinforced with ZrC, and the particles of WC were joined using the friction stir welding (FSW) method. The microstructural and mechanical properties of the welds were investigated using SEM, EDS, and tensile tests. The FSW process resulted in high-quality welds with fine grain structure; the stirred zone has 666% smaller grain size than AA7075 and AA2024 aluminum alloys. The tensile test showed strong and ductile welds. The fracture test showed ductile and less brittle composite joints of AA2024 and AA7075 alloys reinforced with WC and ZrC. The processing parameters in the FSW process significantly affect tensile strength (UTS); therefore, the improvement of UTS with tool speed is much greater than with welding speed. Increasing the tool speed from 400 to 560 rpm increased UTS by 7.1%, and from 560 to 700 rpm by 5.4%. The tensile test results showed that the welds exhibited considerable strength and ductility. Fracture analysis showed that the composite joints made of different AA2024 and AA7075 alloys and reinforced with WC and ZrC were ductile and less brittle. This study showed that FSW can efficiently fuse different aluminum alloys reinforced with ceramic particles.

“…FSW has undertaken various similar or dissimilar alloys welding providing efficient joints. [11][12][13][14][15][16] Researchers have found Friction Stir Welding with High Entropy Alloys as the welding material strengthens the overall result of the weld seam. Research on multicomponent alloys started in 1981, but in 1995 concept of HEA came into the limelight.…”

The work summarizes the review of use of High Entropy Alloy in the Friction Stir Welding. When High Entropy Alloy is utilized in the Friction Stir Welding the resultant mechanical, metallurgical as well as corrosive properties show the influence of HEA base material properties. The Process used to obtain HEA provides base properties affecting the microstructural impact due to heat generation in FSW. Taking into account HEA, FSW too improve the welding properties of the material. The grain size was affected by heat generation and pressure of rotational as well as transverse speed, and could be differentiated in different zones (SZ, HAZ, and TMAZ) and sides (advancing, retreating, top, and bottom). Results of misorentation, HABs, and LABs were influences by the type of recrystallization. GGAE are associated to HABs and SFE to heating phenomenon, so overall it is HEA reaction to the heat generation in different areas and its effects seen in recrystallization of grains.
