of studied materials 2.3 Microstructure characterization For the microstructure observation, the sample was ground and polished with the order of SiC paper, diamond paste and colloidal silica. Specifically, for the optical microscopy (OM, Zeiss Imager A1m) characterization, the sample was prepared by anodic coating at 0 °C in the solution of 2.5 vol.% HBF4 for 30 s at the voltage of 20 V. The field......

The end surface of the shoulder may consist various features like grooves, scrolls... welded joint interface develops [53]. Lower heat input occurring at very high welding speed causes improper mixing of Al-Cu material and results in defects like voids [53-55]. Insufficient flow......
