FEATURES OF DISLOCATION DYNAMICS IN NEAR-SURFACE NANOREGION OF CRYSTAL

The glide of dislocations in a near-surface nanolayer of crystal containing point defects is theoretically analyzed. An analytical expression for the dynamic drag force of dislocations by point defects is obtained. It has been shown that the crystal surface has a significant effect on the dislocatio...

Zusammenfassung:The glide of dislocations in a near-surface nanolayer of crystal containing point defects is theoretically analyzed. An analytical expression for the dynamic drag force of dislocations by point defects is obtained. It has been shown that the crystal surface has a significant effect on the dislocation dynamics in the near-surface region.
