Materials and Methods
The 6 mm thick AA8011 and AA6082-T6 were in the formation of the joint through FSW technique. Table 1 present the chemical compositions and Table 2 present the mechanical properties of the materials. The plates were cut into rectangles of 260 mm × 52 mm. Different material positioning were taken into consideration during welding and processing (see Figure 1). Table 3 shows the parameters used for FSW and FSP. The FSW tool used was made of high-speed steel (HSS) AISI 4140 [25]. The same tool used for FSW was used for FSP.
