Abstract
Equal Channel Angular Extrusion (ECAE) is an innovative technique whose importance has grown in recent years. With this process micrometer or even nanometer grain size is obtained in processed materials. With this grain reduction after thermal treatments, the mechanical properties of the billet are greatly increased. Because the cross section does not change after one passage through the angular channel, it is possible to introduce more deformation in the material, repeating the process several times for the same billet. Depending on how the repetitions are made, different deformation distribution can be obtained in the material. In this work a comparison of routes A and C has been made for an aluminium alloy 5083, between deformation obtained and force required to carry out each passage.
