Abstract

The atomic mechanism of diffusion over low-angle twist boundaries (100), (110), (111) in fcc metals Ni, Cu, Al is studied by the method of molecular dynamics. It was shown that self-diffusion over twist grain boundaries took place by the formation of the chains of displaced atoms along the nuclei of screw grain boundary dislocations, initiated, as a rule, near knots of dislocation net.
