Abstract
The present work has been carried out to utilize the microstructural modification advantage given by Friction Stir Processing (FSP) on an AA6082-T6 metal system of 10mm thick. In the last decade, varying the number of passes on various aluminium alloys FSP has grabbed the attention of many researchers. The main focus of studies was on altering the number of passes, choosing the advancing side (AS) or Retreating side(RS) of tool movement, as well as varying overlapping ratios. In the present work, the authors considered one pass, two passes, and three pass approaches with 100% overlapping and advancing side tool movement. Surface morphology was analyzed through an optical microscope (OM) and scanning electron microscopy (SEM). The process was analyzed for tensile strength, percentage elongation, and proof stress. The study revealed that although the three-pass approach leads to better grain refinement yet, the single-pass approach resulted in higher tensile strength and comparative percentage elongation of the FSPed sample. Additionally, tool wear was also reported lesser in the single-pass approach in comparison to others.

Keywords
