Abstract

In this study, firstly all of Al-7075-T6 alloys were joined by the friction stir welding (FSW) method then the samples were divided into four groups. First group of samples were used directly. The second group of samples was burnished. Third group of samples were aged and the last group of samples was subjected to both re-aging and burnishing process. It was compared the tensile and bending strengths of all prepared specimens. After the FSW process, only the second aging process increased the tensile strength. There is no effect on the tensile strength of the burnishing process. The bending strength has improved only the re-aging process without burnishing operation or only burnishing without the second aging process. In the friction stir welded Al-7075-T6 materials, it was concluded not to have a significant effect on the mechanical properties of the burnishing process. However, the hardness values of the materials were increased by both the re-aging and the burnishing process.
