Abstract
The dynamics of a high-angle tilt boundary in a triangular lattice with a truncated Lennard-Jones potential has been simulated by the method of computer molecular dynamics. Boundary migration was observed at various temperatures above a threshold, and was interpreted in terms of small steps involving coupled sliding and migration. In some cases, the simulation proceeded to the annihilation of a pair of boundaries with the attendant release of the boundary free energy and delocalization of the boundary free volume.This publication has 12 references indexed in Scilit:
