and the material with which it is to be made. The fundamental goal of process design in extrusion is to produce industrial parts with high quality, precise dimensions in a most economical way. In this endeavor process optimization is of immense importance. In this thesis Equal Channel Angular Pressing (ECAP) is modeled using finite element method and the evolution of strain in the specimen, extrusion force and forming energy needed during severe plastic deformation for various input parameters are
