Effective climb (see text): a two dislocations approach each other (center of the figure); b they arrive at a distance comparable to two interatomic spacings, thus inducing a strong distortion in the surrounding lattice; c a local slip of atoms induces a rotation of the original Burgers vector (atomic displacements are represented by arrows).
