Extended Defects in Copper and Their Interactions with Point Defects
The atomic configuration of the glissile edge dislocation and the intrinsic and extrinsic sessile Frank dislocations in copper have been obtained using an atomic model of the copper lattice with an interatomic pair potential extending through second neighbors. The extent of dissociation into Shockley partials of the glissile edge dislocation is obtained by an iterative procedure involving continual readjustments to the boundary displacements. The atomic model has also been used to estimate the interaction energy between intrinsic point defects and the three dislocation types when the point defects are in proximity with the dislocations.
