This work aimed to study the microstructural characterization and mechanical behavior of AA2139 T3 and T8 aluminum alloys joined by FSW - Friction Stir Welding. The microstructural analysis has been done using optical microscope and scanning electron microscopy, and the mechanical analysis were evaluate through microhardness testing and conventional tensile test using the ARAMIS system. Each alloy were welded using the same welding parameters and the same tool in order to evaluate the joint quality for both heat treatment used for this work, T3 and T8. The result showed sounds joints for both heat treatments, although with better mechanical properties for the alloy AA2139 T3.
