Abstract
This paper covers the problematic of creating ultra-fine grained metals by severe plastic deformation methods. Unlike surface treatment technologies which create thin layers of nanomaterials, severe plastic deformation methods can create nanosized grains almost within whole volume by introducing high values of effective strain. In this paper, compression by V-shape dies has been presented as method for creating ultra-fine grained metals. Friction coefficient between the V-shape dies and sample has been varied in order to find its influence on effective strain values at the center of specimens. Grain size at the sample has been analysed by using transmission electron microscope.
