Question #3> Dislocation intersections of partial dislocations (extended dislocation) Extended dislocations on the plane A are moving towards extended dislocations on the plane C. In order to understand dislocation intersections of partial dislocations, we need simple assumption; i) Intersections only occur for perfect dislocations; ii) Interaction of the elastic strain fields of the leading partial dislocations makes the constriction of dislocations. Draw the dislocation lines after intersecting each other, with breaks on appropriate planes. b of unextended dislocation 6 ? A
