ABSTRACT:As a solid-state joining technology, friction stir welding ( FSW ) possesses many advantages, e. g. low stress, small distortion and non-pollution. Titanium alloys have been widely used in the important fields such as aerospace, which can be welded by FSW. So far, FSW of titanium alloys has attracted more and more attention. Recent advances in FSW of titanium alloys were introduced from aspects of microstructure, mechanical property, tool wear, and hybrid technol-ogy. The further trends of FSW of titanium alloys were presented briefly.
