Abstract

In this paper, we present a new set of conditions which can be used for imaging {113} defects. These conditions have the advantage of allowing the simultaneous imaging of all the variants of the defects. They can be used for building up accurate size-histograms or for checking the occurrence of the different variants. Making use of these conditions, we revisit the well- known experiments of the dissolution of the {113} defects and pinpoint some specific features of defect evolution during annealing which were not evidenced in previous works. The new results are discussed and are definitely found to be well-explained in the framework of a non- conservative Ostwald ripening.
