Friction stir processing is a solid-state process to modify microstructure and mechanical properties of sheet metals and as-cast materials. In this process, stirring action of the tool causes the material to intense plastic deformation that yields a dynamic recrystallization. In this study, the effect of friction stir processing (FSP) and process parameters on microstructure, mechanical properties, wear resistance, and corrosion behavior of AA5083-O has been investigated. Results show that FSP leads to finer and homogenized grain structure, as well as changes in hardness, corrosion resistance, and wear resistance of the material.
