Web7. The type of dislocation discussed above is called edge dislocation. For edge dislocation, the slipping direction is perpendicular to the line of imperfection. 8. Edge dislocation has “sign” because the plane can slip in one of the two possible directions, either towards to or away from the dislocation line.

WebTheory of Dislocations: Dislocations are defined as the irregularities in the structure of metals. These arise from misplacement of bonds of the atoms in a part of the plane of a crystal and are considered to be weak centres. They are instrumental in affecting the breaking stress and plastic and chemical properties of crystals.
