Experimental and numerical investigation on under-water friction stir welding of armour grade AA2519-T87 aluminium alloy
Friction stir welding (FSW) is a promising welding process that can join age hardenable aluminium alloys with high joint efficiency.However, the thermal cycles experienced by the material to be joined during FSW resulted in the deterioration of mechanical properties due to the coarsening and dissolution of strengthening precipitates in the thermo-m
