Abstract
2024 aluminum alloy sheets in T4 temper were welded successfully by friction stir welding (FSW) technique. When the welding travel speed was 300 mm min–1, tensile strength reached a maximum value (294 MPa). The precipitated phase is mainly metastable U (AlCuMg) of reinforced phases in thermo-mechanically affected zone (TMAZ). Lots of the AlCu3 black particles precipitated on the grain boundary of TMAZ. However, a large number of Cu2Mg black granular precipitates were observed in the WN region.

Key words
