摘要

    摘要
  • 摘要: 采用自行设计的无匙孔搅拌摩擦点焊方法对6061铝合金和DP600镀锌钢进行点焊(钢上铝下),利用扫描电镜、能谱仪及拉伸试验对接头的微观组织和力学性能进行研究.结果表明,搅拌头旋转频率为1200 r/min、预热时间为6 s和搅拌针长度为3.2 mm时,接头抗剪载荷可达11.2 kN.接头表面平整美观无匙孔;接头由搅拌区和扩散区组成,搅拌区内钢以弯钩状分布嵌入铝基体,形成牢固的机械连接;扩散区内铝和钢依靠界面上的金属间化合物连接,连接方式为冶金结合.接头断裂位置为扩散区化合物层与铝基体界面处,断口呈河流状的解理台阶,属于脆性断裂.
    Abstract: FSSW without keyhole of Al6061 and DP600 zinc-coated steel was carried out by using the equipment designed by our team (top steel sheet-bottom Al sheet). Using scanning electron microscope, energy spectrometer and tensile test on the microstructure and mechanical properties of joint were studied. The results showed that the mixing head speed was 1200 r/min, the preheating time was 6 s and stirring needle length was 3.2 mm and joint shear resistance reached 11.2 kN. The surface of joint was smoothly without keyhole. Welding joint was composed of the stir zone and the diffusion zone, stir zone to hook shape the distribution of embedded steel in the aluminum matrix and finally form strong mechanical connection. The diffusion zone of aluminum and steel's connection depended on the interfacial intermetallic compounds. Connection mode was metallurgical combination. The fracture of welding joint's position was in between of the interface layer and the aluminum substrate. The distribution of river-shaped fracture was cleavage steps, so the mode of fracture belonged to brittle fracture.
