The manufacturing of a functional hollow mechanical element or ring of the AA5083 alloy previously equal channel angular
extrusion (ECAE) processed, which presents a submicrometric microstructure, is dealt with. For this purpose, the design of two
isothermal forging dies (preform and final shape) is carried out using the design of experiments (DOE) methodology. Moreover,
after manufacturing the dies and carrying out tests so as to achieve real rings, themechanical properties of these rings are analysed as
well as their microstructure. Furthermore, a comparison between the different forged rings is made fromECAE-processedmaterial
subjected to different heat treatments, previous to the forging stage. On the other hand, the ring forging process ismodelled through
the use of finite element simulation in order to improve the die design and to study the force required for the isothermal forging,
the damage value, and the strain thematerial predeformed by ECAE has undergone.With this present research work, it is intended
to improve the knowledge about the mechanical properties of nanostructured material and the applicability of this material to
industrial processes that allow the manufacturing of functional parts.
