Numerical Simulation of Channel Angles and Their Combination Influence on Plastic Deformation Behaviour of Pure Al Processed by Equal Channel Angular Pressing
Equal channel angular pressing (ECAP) is one of the most efficient methods of severe plastic deformation (SPD) for obtaining bulk nanostructured materials. The ECAP die consists of two equal channels that meet at an angle, usually between 90° and 135°. In the present study, the effect of ECAP die channel angles and their combination on the plastic deformation behaviour of pure Al during ECAP under friction and frictionless conditions were investigated. A 2-D finite element modelling was used in order to analyse the plastic deformation behaviour as the material passes through the die. The properties of commercially pure aluminium (Al) have been selected in order to perform FEM simulations. A sound knowledge obtained for the plastic deformation (material flow) and understanding the relationships between plastic deformation and mechanical properties of pure Al.
