Abstract
Bulk nanostructured materials represent the application of nanotechnology in the engineering material area. Severe Plastic Deformation (SPD) and in particular Equal Channel Angular Pressing (ECAP) are efficient and low cost top-down methods for producing ultrafine or nanostructured bulk materials. Alluminum alloys are very popular materials used for production of ultrafine-grained and nanomaterials by SPD. Understanding both the contact phenomenon at the interface between die and the workpiece in terms of material flow and phenomena associated with strain and forming load in ECAP process becomes important. In this paper, a tridimensional Finite Element Analysis of ECAP was performed for Al-Mg 5083 alloy.
