Nanostructural Formation by Severe Plastic Deformation

At the present time the topic of intense research is the refining of various type material structure, which has the low value of the basic deformation resistance during the bulk deformation processes by severe plastic deformation - SPD at the ambient temperature. The purpose of SPD is to obtain the result structure at the nm level (ultrafine structure) from the original mm level one. There are two ways of SPD realization: Equal-channel angular pressing - ECAP, and High-pressure torsion - HTP realized by high stress. In this study, the influence of severe plastic deformation (SPD) realized by ECAP procedure on structural, mechanical and plastic properties of ARMCO-Fe was inestigated. Mathematics simulation by FEM was applied, too.
