Abstract

The effect of equal canal angel pressure deformation on the stress - strain curves of high deformed materials was studied. The influence of the deformation degrees on dislocation and cell structure evolution was analyzed. The dominant features of nanocrystalline structure formation under severe plastic deformation were discussed. The structural sensitivity of the mechanical properties of high deformed Fe-Armco was studied.
