Description
An experimental study was carried out to investigate the link between the microstructure and the mechanical and corrosion properties for a friction stir welded aerospace aluminium alloy 7349-T6 (Al, 1.4-2.1%Cu, 1.8-2.7%Mg, 7.5-8.7%Zn) developed for wing box applications. FSW was carried out on plates of thickness 10 mm. Microhardness testing and tensile testing were carried out and microstructure was examined. Accelerated intergranular corrosion tests were performed. Tensile properties of various localised areas across the weld zone were determined. The evolution of intergranular precipitation during FSW was examined. The mechanical and corrosion behaviour of the welds are discussed in terms of the microstructural changes.
