Abstract

In this paper the method of molecular dynamics used to studythe interaction of lattice vacancies with symmetric tilt grain boundaries (GBs) in aluminum. A linear dependence between the numberof captured vacancies and the distance to the GB’s plane was found. The average rate of vacancy migration to the border decreases exponentially with increasing distance between the plane of the GB and the vacancy. Capture’s radius is limited to 2-3 lattice parameters and increases with increasing temperature. Definedfour types of boundaries in different ways of interacting with lattice vacancies.
