Simulation of deformation behaviour of Aluminium 7075 during Equal Channel Angular Pressing (ECAP)

This paper presents a finite element simulation of equal channel angular pressing (ECAP) since it is one the most common and successful severe plastic deformation techniques. study reports influence significant factors influencing ECAP technique. Through simulation, effect die geometry, workpiece speed on effective strain distributions, damage, loads, were investigated. The method different material models also presented. Additionally, prospective expansion future applications are herein highlighted. From results, geometry 90° imparts highest strains during ECAP. specimens rectangular susceptible to cracking damage as compared circular samples. It was found that very high processing speeds (>7mm/sec) undesirable they cause internal stresses structure workpieces. Besides, at room temperature can achieve homogeneous distribution with minimum sample damage.
