Abstract: The present study discusses the trials of friction stir welding (FSW) on the Zn-22Al superplastic alloy. The effect of different process parameters of FSW tool on the mechanical behaviour of the welded zone has been discussed. The results are discussed in terms of mechanical properties and microstructure observations. A new developed FSW tool which was investigated in our laboratory was used in the experiments to investigate the structural changes of microstructures of the material as well. Results revealed a fine grain structure after FSW within the stir zone.
