Abstract

Atomistic computer simulations have been carried out to investigate edge dislocation dipole configurations in metals. A non-pair interatomic potential was used and the stress was kept constant as a boundary condition. Narrow edge dislocation dipoles of vacancy and interstitial type show significant differences. Several metastable configurations of vacancy-type dipoles were found. Our results are discussed with respect to the suggested annihilation of narrow edge dipoles in persistent slip bands of fatigued metals.
