This work presents a study related to the achievement of a nanometric structure in AA3103, employing severe plastic deformation
processes (SPD), in this case equal channel angular pressing (ECAP). The changes in the mechanical properties and in the
microstructure of AA3103 were studied after being processed by ECAP. Subsequently, scanning electron microscopy was used to
determine the evolution of the microstructure after different thermal treatments on the material processed by this severe plastic
deformation process. Furthermore, a more profound knowledge of the changes in the mechanical properties of this aluminium
alloy was obtained. It was demonstrated that with different appropriate combinations of thermal treatments and ECAP processing,
it is possible to significantly improve the mechanical properties through obtaining submicrometric grain size structures. [--]
