N2 - The interaction between dislocation loops of interstitial nature with ½ and Burgers vectors
and point defects in Fe has been studied molecular dynamics. Comparative calculations have been carried
out using two interatomic potentials for pure Fe ([G.J. Ackland, M.I. Mendelev, D.J. Srolovitz, S. Han, A.V.
Barashev, J. Phys.: Condens. Mater. 16 (2004) 1; S. Dudarev, P. Derlet, J. Phys.: Condens. Mater. 17 (2005)
7097]). The results of this study are range and energy of the interaction as functions of size and mutual
position of defects. The applied potentials predict somewhat different strain field structure for
loops and therefore different lengths of interaction. However, both potentials suggest that, contrary to
common belief, the distance of cluster-defect interaction within the glide prism of a ½ cluster is
significantly longer than that of a cluster of similar size, in spite of the longer Burgers vector in
the latter case.
