Abstract : Friction stir welding is one of the promising techniques to join dissimilar aluminum alloys. In this study, the friction stir welding technique is implemented to enable a sound butt-joint between aluminum alloy AA5052 and AA6061. The study investigates the influence of conventional heat treatment and newly-devised cyclic treatment on the properties of the friction stir weldment. The results indicate that the newly-devised cyclic heat treatment increases the microhardness by ~22%, tensile strength by ~22%, and ductility by 20% than the conventionally heat-treated specimens. The mechanism of property enhancement in the weldment is comprehensively correlated with the microstructural evolution.
