摘要：
The enhanced mechanical properties of crystalline materials is usually linked to very small grain sizes. ECAP is a technique for developing an ultrafine-grained microstructure by introducing a severe plastic deformation in bulk materials by simple shear with no changes in their cross-section. The AA5083, an Al-Mg-Mn commercial alloy, is known for its superplastic behavior. The room temperature mechanical properties of the extruded alloy were investigated through hardness measurements and tensile tests. Mechanical properties evolution during annealing is also considered. Finite Element Modeling is used to predict the ECAE behavior in different extrusions conditions and compared with experimental processes carried out in similar conditions.
