formation of new closed loops. We thus have multiplication of dislocation loops and there is no necessity for nucleating new ones, although some may be nucleated at a distance from the existing ones.
The observations of decorated dislocations in fluoritec4) suggest that such a mechanism can operate under climb conditions.
It is clear that the same mechanism can take place starting, not from an initial prismatic loop, but from a screw dislocation (or one which is approximately so) inherited from a seed, or another substrate.
In practice, several "sources" of rings with different Burgers vectors will be operating and their intersections will result in the formation of the dislocation network.
