Microstructure,　texture　and　mechanical　properties　of　electrically　assisted　friction　stir　welding　(EFSW)　of　Ti6Al4　V　alloy　were　investigated.　The　base　material　(BM)　and　the　heat-affected　zone　(HAZ)　have　a　coarse　equiaxed　structure,　and　the　fine　equiaxed　structure　was　observed　in　the　stir　zone　(SZ).　The　boundary　between　the　SZ　and　the　HAZ　changed　abruptly　from　the　FSW　joint　to　the　EFSW　joint　to　make　it　smooth.　The　BM　and　the　HAZ　have　a　strong　prismatic　texture　{10　(1)　over　bar0}　and　the　texture　of　the　SZ　is　randomly　distributed.　Hardness　of　the　joints　was　explained　by　grain　size,　loss　rate　of　elemental　Al　and　dislocation　density,　as　well　as　the　advantages　of　the　EFSW　process　in　terms　of　improving　mechanical　properties　as　influenced　by　microstructure　and　texture.
