چکیده مقاله
In this study, the effect of friction stir post processing on the microstructural characteristics and mechanical properties of GTAW Gas Tungsten Arc Welding welds in the aluminum 5052 alloy were evaluated Friction stir processing destroyed the grains dendritic microstructure and due to dynamic recrystallization resulted in very fine and equiaxed grains structure in the fusion zone The hardness of the friction stir processed welds significantly improved because of microstructure grain refinement Besides, the friction stir processed weld demonstrated higher ultimate tensile strength ~275 MPa and superior elongation 31 1% as compared to those of the base metal and unprocessed weld
