Is it possible for a perfect dislocation to dissociate in to two other perfect dislocations bounded by a planar fault?

Generally in alloys and Intermetallics, we have studied a perfect dislocation having Burgers vector b1 dissociates in to two partials having Burgers vector b2 and b3 bounded by 2D defects such as...
