Abstract
The results of theoretical analysis of fields of local internal stresses and their gradients of nonequilibrium substructures in metal materials during the formation of nanostructural states in conditions of intensive deformation are presented. Possibility of use of disclinational approach within the continual theory of defects for description of the above mentioned states at nanoscale structural level is shown. Dipole and quadrupole configurations of wedge partial disclinations are considered. It's shown that the size of local internal stresses and their gradients can reach P ≈ E/50 and ∂P/∂x ≈ 0.02 nm-1 respectively. The calculating experiment demonstrates that high values of local internal stresses and their gradients in the field of elastic distortions can be described by multipole configurations of partial disclinations like dipole/quadrupole. The problem of the nanodipole configuration of partial disclinations and its disintegration on quadrupoles system is considered.
