The maximal short-range (SR) component (a totally irreversible slip) can be written as ( ) ( ) max 3 1 6 3 1 S cl S SR R R δ δ −   =  + −   . (2) Due to an enormous variability in the characteristic microstructure distance in engineering materials and for the sake of simplicity, one can divide the grains (or interparticle spacings) into two categories; to those of SR ≥ SRc (maximal level of RICC, SR ≥ 1) and those of SR < SRc (no RICC, SR → 0), where Rc c pS d r= is a critical boundary value of about 0.5 (SRc ∈ 〈0.2, 1〉 [8]).

By continued pressing a more advanced deformed substructure was obtained after conducting two deformation passes (8 pressings), which yielded the equivalent strain of ε ~ 2.32, four deformation passes (16 pressings, ε ~ 4.64) and 8 deformation passes (32 pressings, ε ~ 9.28).
Locally observed, the more advanced process of polygonization contributed to formation of regular equiaxed subgrains free of dislocations.
Considering transformation characteristics of deformed structure it appears that the mechanism, which contributes for microstructure refinement, as concerns of the only advanced deformed substructure transformation within macrosheared bands to polygonized subgrains, excluding primary stage of the large grains subdivision by macroshearing, local dynamic recovery is active and not more advanced microshearing.
