Abstract

Since it has recently become an important subject to study the interrelation between a dislocation loop and a straight edge dislocation because of dynamic behaviors of small dislocation loops under irradiation condition, the simulation studies were made in model Fe lattice. It was found that dislocation cores both for a loop and a dislocation can be expressed by the regular array of three types of crowdions and have stable positions of b/3 periodicity, but this regularity and periodicity are disturbed as the decrease of the loop size. The relation between a dislocation core and crowdion types are also studied. Furthermore, this change gives rise to the increase of the inherent lattice resistance (Peierls stress) for the dislocation loops.
