Friction-stir-welded joints of 16-mm-thick plates of AA7075 aluminum alloy have been studied. The macrostructure of the weld region over the thickness of the plates and microstructures of various regions of the welded joint were determined using optical and transmission electron microscopes. Tensile testing of the welded samples was conducted, and the average values of the ultimate strength and yield point, as well as relative elongation were calculated. The Vickers hardness profiles in the… CONTINUE READING
