| Abstract: | Double-sided friction stir welding was applied to connection of 6061-T6 aluminum alloy plates,the microstructure and mechanical properties of the joints were investigated.The results show that the microstructure undergoes different changes in the through-thickness direction,the tensile strength of the joint reaches 218MPa,70% that of the parent material.The re-solution and over-aging of the strengthening phases caused by welding thermal cycle have a great effect on the strength degradation,and the thermal m... |
