Recent developments in nanostructured products draw considerable attention to ultrafine grained materials. These materials are normally manufactured by different severe plastic deformation (SPD) methods. In the present study, analytical models and finite element method (FEM) are used to calculate strain imposed to a specimen that was deformed by equal channel angular pressing (ECAP). In additio...

Over the last two decades, many researchers have developed a variety of stainless steel-based medical implant types,taking full advantage of nanostructuring technologies. In this paper the application, fabrication and development of nanostructured stainless steel based materials with new composition for medical implants will be discussed. It is well established that application of severe plasti...

Abstract The exact calculations of the stress and strain distributions based on controlling equations for a forming process with large deformation are often difficult. To circumvent such difficulties, some analytical methods upper-bound analysis slip-line field theory have been established by making number simplifying assumptions regarding material properties modes. In this work an model was su...
