“…FSW is used in the aerospace, automotive, railway, and shipbuilding industries. It is typically applied to butt joints on large Al parts [16]. Several advantages, including high-quality joints, low-energy process, precise external control, low pollution, and lack of special sample preparation, are provided via FSW [17][18][19].…”

5083 aluminium (Al) alloy materials have extensive structural applications in transportation industries because of their high strength-to-weight ratio and corrosion resistance. However, under conventional fusion weldings, these materials are limited by their porosity, hot cracking, and distortion. Herein, friction stir welding (FSW) was performed to join a similar AA5083 alloy. A post-weld cold-rolling (PWCR) process was applied on joint samples at different thickness-reduction percentages (i.e., 10%, 20%, and 40%) to identify the effect of strain hardening on the microstructure and mechanical properties of the friction-stir-welded joint of AA5083 while considering the serration-flow behaviour at stress–strain curves and dislocation density of the post-weld cold-rolled (PWCRed) samples. FSW induced a 20% reduction in the tensile strength of the joint samples relative to the base metal. PWCR also reduced the average grain size at the nugget zone and base metal because of the increase in plastic deformation imposed on the samples. Furthermore, PWCR increased the dislocation density because of the interaction among dislocation stress fields. Consequently, the tensile strength of the friction-stir-welded joint increased with the increased cold-rolling percentage and peaked at 403 MPa for PWCRed–40%, which significantly improved the serration-flow behaviour of stress–strain and welding efficiency up to 123%.

“…Friction stir welding (FSW) is emerging as a preeminent technology for solving this obstacle. This FSW is suitable for joining light weight alloys such as aluminium alloys for both similar and dissimilar welding [2,3]. Furthermore, this FSW is recognized as a green technique in metal joining with high energy efficiency and versatility.…”

Abstract. Aluminium alloy 6063-T5 plates were joined by friction stir welding technique. The fatigue crack growth (FCG) in the thermo-mechanical affected zone (TMAZ) and in the heat affected zone (HAZ) of the welding was examined at 200 o C. Although the grain microstructure of the TMAZ was significantly refined in comparison with that of BM, the FCG rate in TMAZ and base metal was shifted a comparable amount when the test temperature was elevated from room temperature to 200 o C. In the metallurgical view, the FCG rate in the fine grain TMAZ was higher than that in coarse grain HAZ and base metal site.

“…It is well known that the FSW is thermomechanical processing and result of severe plastic deformation and microstructural changes. The welded zone possesses various inhomogeneous microstructure features and mechanical properties [1][2][3]. With aluminum alloy 6063, a heat-treatable alloy, the effect of temperature on the microstructure and/or mechanical properties during welding is unavoidable.…”
