摘要	The microtexture evolution, hardness distribution and tensile properties of the friction stir welded joint of 7050 aluminum alloy with a thickness of 5 mm were studied and compared with the tensile properties of the complete welded joints. The results show that the base metal is mainly for the substructure, with (011) [100] Goss texture, (112) [111] copper texture and (001) [100] Cube texture. Dynamic recrystallization occurred in the weld nugget zone, mainly existing in [100]//WD, [110]//WD, [111]//WD fiber texture. There are (111) [110] shear texture, (110) [112] brass texture, (100) [012] and (100) [012] recrystallization texture in the thermos- mechanically affected zone of advancing side; the thermo-mechanically affected zone of retreating side is (001) [110] rotating cubic recrystallization texture and (112) [111] copper texture, mainly due to different thermal-mechanical action in each microzone. The hardness of the weld zone is "W" type distribution, and the lo-west hardness is located in the heat-affected zone of retreating side. The tensile strength of the advancing side and the retreating side of the weld is 496.9 MPa and 505.2 MPa, respectively, reaching 88% and 90% of the tensile strength of the base metal. The tensile strength of the weld nugget zone is 440.4 MPa. The tensile strength of the complete welded joints is the lowest, 415.7 MPa. © 2020, Materials Review Magazine. All right reserved.
