Tensile Strength, Hardness, and Joint Efficiency of Similar AA2024 and AA7075 Friction Stir Welded Joints with Post-Weld Treatment
Although Friction Stir Welding (FSW) reduces defects associated with conventional fusion welding of high-strength aluminium alloys such as AA7075 and AA2024, the resulting joints may still exhibit microstructural heterogeneity, residual stresses, and reduced joint efficiency. Limited studies have investigated cryogenic...
