Abstract Scope |
Coupled cluster dynamics and discrete dislocation dynamics can study the interactions between point defects and particular dislocation microstructures. In particular it allows a complete description of the collective effects of long and short range strain field interactions on point defect flux. The sink strength of representative 3d dislocation networks for a variety of defects is computed in this study using the coupled framework. A probability distribution of the dislocation bias factor is found, which accounts for curvature and configuration effects, the character of the segments, and the superposition of strain fields. In addition to global properties like the bias factor, these effects motivate wide variations in local quantities such as local defect supersaturation and the current of point defects into dislocations. |
