As shown in Fig. 11-1, dislocations will ordinarily take the form of curves or loops, which in three dimensions form an interlocking dislocation network.
In considering a dislocation line, it can be edge, screw or mixed type but can be resolved into edge and screw components.
For example, in 13-1, the dislocation loop is pure screw at point A and pure edge at point B, while along most of its length it has mixed edge and screw components.
