Abstract


Nowadays, Equal Channel Angular Processing (ECAP) is one of the most appealing and potentially efficient Severe Plastic Deformation techniques (SPD) for fabricating Ultrafine Grained (UFG) and Nanostructured materials (NS) with sufficiently improved mechanical properties which has enabled this technique to be used in industrial applications. In this study, commercially pure aluminum was processed by ECAP through route A for up to 4 passes. A Finite Element (FE) analysis was carried out and compared to the experimental findings in order to investigate the effects of the geometric and the process’ parameters on the plastic deformation behavior of the work-piece during the ECAP process. The number of passes was selected as an input factor, while hardness values and compressive properties were modeled as the response. The total imposed stresses and strain as a function of the number of passes were examined. The FE analysis were carried out, yielding favorable results, concurring perfectly with the experimental findings and the microstructural evolution.
