Recent studies have demonstrated that FSW provides potential for refining the grain size of a joint material down to the submicrometer level in the friction stir welded zone. As well known, the reduction in grain size to the submicrometer level has significant advantages, e.g. an increase in the tensile strength with little or no corresponding reduction in the overall ductility at ambient temperature and a possibility of achieving superplasticity at elevated temperatures. The present work was aimed to investigate the practicability of grain refinement in a 6N01 aluminum alloy by using FSW technique and to examine mechanical properties of this friction stir welded (FSWed) material at room temperature, such as the tensile properties and Vickers hardness
