PACK SLIP BANDS FORMATION IN FCC SINGLE CRYSTALS * Alfyorova E.A. 1 , Ph.D. (Physics and Mathematics), Associate Professor, e-mail: katerina525@mail.ru Lychagin D.V. 1, 2 , D.Sc.

The analysis was carried out on various FCC materials (single crystals of pure metals of nickel, aluminum and Ni 3 Fe alloy with short-range order and long-range order). We have established that slip traces and pack slip bands have different graphs of ordinate density function. This is typical for all materials that we reviewed. Using the methods of fractal analysis, we estimate the ability of slip traces and pack slip bands to self-organization. At the microlevel, self- organization is carried out through tuning in the dislocation subsystem, and at the mesolevel due to a correlated shift in parallel octahedral planes. Keywords slip traces, pack slip bands, self-organization, single crystal, dislocation subsystem * The reported study was funded by RFBR, according to the research project No. 16-32-60007 mol_а_dk
