The mechanical properties and corrosion behavior of 6061-T6 Aluminum alloy and three fabricated composites from this alloy were experimentally investigated in this paper. The composites were made during two passes of friction stir processing. Alumina powder (𝐴𝑙 2 𝑂 3 ) was used as reinforcing particles. These composites included a powder-free sample, a micro-alumina Based on the research conducted in this study, the following conclusions can be obtained:
