摘要 通过拉伸、弯曲、硬度试验以及金相分析等对6082铝合金FSW焊接接头的力学性能与显微组织进行了研究。结果表明.以转速1500r/min、焊速600mm/min的参数焊接6082铝合金时,其接头具有较好的抗拉性能,板厚6mm和3mm焊接接头的抗拉强度分别为母材的77.23%和78.86%;正弯断裂位置集中在HAz处,角度约90°,背弯断裂位置集中在焊缝中心,角度较小;硬度试验显示两侧热影响区处均软化;6082铝合金FSW焊接接头焊核区和轴肩影响区发生了动态再结晶,形成了细小的等轴晶组织,热机影响区组织发生了较大程度的变形;热影响区仅受热循环的作用,组织略有粗化。 Microstructures and properties of 6082 aluminum alloy weld joint are investigated by room-temperature tensile, bending, hardness test and metallographic analysis. The results show that the joints of 6082 aluminum alloy welded with the rotation rate 1500r/min and welding speed 600mm/min parameters by means of FSW have good tensile strength,the tensile strength of the joints which of thickness 6mm and 3mm are 77.23% and 78. 86% of the base material respectively. The face bending failure concentrates in HAZ at the angle of about 90° and the back bending failure concentrates in the weld center at the small angle. Hardness test shows softening areas in both sides of HAZ. Weld nugget and axis shoulder-affected zone of 6082 aluminum alloy FSW welded joint occurres dynamic reerystallization,forming a small equiaxed organizations. TMAZ occurres in a larger degree of deformation and organization of HAZ has a little rough by the role of heat cycle only.
