Abstract

Severe plastic deformation is one of the most effective methods for applying high plastic strain to metallic specimen. Constrained Groove Pressing (CGP) and Repetitive Corrugation and straightening (RCS) are preeminent in this field. There are several similarities between these two processes, however, there are some differences in applied strain. Consequently, the deformation process is really crucial in case of method. In this study, AA 1070 Aluminum alloy has been utilized in order to investigate the behavior of deformation using stated methods. Therefore, filling of the die, effective strain distribution and required load to perform the process were analyzed using Finite Element Analysis (FEA) for a single pass of deformation. To evaluate homogeneity of applied deformation, inhomogeneity index of effective strain was considered. The simulations are carried out using commercially available DEFORM-3DTM software and for validation, the results were compared to former reported researches. It was revealed that the amount of filling of the die was greater for CGP in comparison with RCS. As a result, it is FEAsible to repeat the process in order to obtain high plastic strain. Furthermore, the deformed specimen experienced more plastic strain for CGP. In addition, this strain distribution was imposed homogeneously thus the mechanical properties can be improved uniformly in the specimen.
