Mathematical simulation and experiments are used to study plastic strain in nickel 001 single crystals. It is shown that the crystal exhibits self-organization of plastic strain at all scales, and the most developed effect is observed at the microlevel. Processes of self- organization of plastic strain are determined for micro- and mesolevels. At such levels, the processes involve correlated creation and annihilation of dislocations and correlated shear in parallel gliding planes, respectively. Owing to the above processes, the strain components are quasi-periodically distributed over the face, so that crystal integrity is maintained under load.
