Aluminum alloys have attracted significant interest due to their high potentially lightweight materials for corrosion resistance, specific strength, reasonable formability and recycling efficiency. Also, the strength and corrosion resistance of aluminum alloys can be improved by alloying element addition and thermo-mechanical treatment process, which allow aluminum alloys to have optimum grain structure suitable for various applications. In the present work, the effect of AlTiB and Mn addition on the microstructure and tensile properties of Aluminum alloys. The Aluminum alloy melt was held at 800℃ and then poured into a mould at 200℃. Aluminum alloys were hot-extruded into a rod that was 12mm in thickness with a reduction ratio of 40:1. The microstructure of specimens was examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), optical microscopy (OM). The mechanical properties of the Aluminum alloys were maintained by a tensile test.
