| 摘 要： | 分别采用固相扩散焊和瞬间液相扩散焊方法焊接6063铝合金。采用金相显微镜对扩散界面附近的显微组织进行了分析;采用万能试验机测试了焊接接头的抗拉强度。试验结果表明，在连接同种铝合金材料的情况下，固相扩散焊相比瞬间液相扩散焊能够获得更为良好的接头性能。在焊接温度540℃、焊接压力8 MPa、保温时间80 min时，固相扩散焊接头区域成分均匀，没有空洞等缺陷，抗拉强度为122 MPa，达到同种热处理条件下母材抗拉强度(130 MPa)的94%。

| Abstract: | 6063 aluminum alloy was welded through solid-state diffusion bonding and transient liquid phase bonding, respectively. The microstructure near the diffusion interface was observed by metallographic microscope. The tensile strength of the joints was tested on universal testing machine. Test results show that solid-state diffusion bonding can obtain better joint performance than that of transient liquid phase bonding when connecting the same aluminum alloy. In the case of welding temperature 540 ℃, welding pressure 8 MPa and holding time 80 min, the composition of joint obtained by solid-state diffusion bonding is uniform without cavity defects. The tensile strength is 122 MPa, which is 94% of the base metal under the same heat treatment condition. |
