• The transmission electron microscope investigation of thin foils of aluminium alloys has revealed the operation of spiral type of Frank-Read sources induced by high-intensity and fine-focus illumination. A part of a dislocation whose Burgers vector lies in a slip plane has rotated around a point of emergence of the other part of the dislocation not lying in the same slip plane. The sources have emitted several dislocation loops in their life time during the observation. The nature of the dislocation has been defined from the cross-slip traces. The other types of multiplication processes have been observed.
