不同的搭接接头的铝和不锈钢首先摩擦搅拌焊接刀具与切割销。结果表明，该方法可以得到良好的节理。当销子插入下部钢板时，钢闪光插入金块底部两侧的上部铝中形成宏观联锁。在铝/钢界面处形成了薄的金属间化合物（IMC）层和微联锁的机械结合。此外，界面附近的铝也通过晶粒细化和IMC颗粒得到强化。因此，消除了钢闪光产生的宏观联锁效应，接头的抗剪强度达到89·7 MPa，甚至高于母材铝的抗剪强度。
Dissimilar lap joints of aluminium and stainless steel were first friction stir welded by the tool with a cutting pin. The results showed that sound joints could be obtained by this method. When the pin was inserted into the lower steel sheet, macrointerlocks were formed by the steel flashes plugging into the upper aluminium at both sides of the nugget bottom. At the aluminium/steel interface, a thin intermetallic compound (IMC) layer and the mechanical bonding of microinterlocks were formed. In addition, the aluminium near the interface was also strengthened by grain refinement and IMC particles. Therefore, the beneficial effect of the macrointerlocks provided by the steel flashes was removed, the shear strength of the joint reached 89·7 MPa, which was even higher than that of the base metal of aluminium.
