Interaction mechanisms of glissile loops in FCC systems by the elastic theory

The elastic theory calculations are conducted to clarify the interaction between a large dislocation loop and a small glissile loop in face-centered-cubic systems. In the parallel Burgers vector case, the interaction force changes from repulsive to attractive when the small loop moves along its glide cylinder. In the perpendicular Burgers vector cases, the interaction strongly depends on the spatial position of the glide cylinder of the small loop from the center of the large loop. There are attractive regions in any combinations of the Burgers vectors and spatial positions calculated in this study, which may induce the loop decoration.
