In this work, the relationship between heat input during friction stir welding (FSW) and the microstructure formed in the stir zone of a modern heat-treatable aluminium alloy 2519 was studied. Electron back-scatter diffraction technique (EBSD) revealed that microstructure consists of fine grains. In addition, it was found that grain size does not exceed 2 mkm.
