“…Association of large voids with various precipitates (G, η, Laves etc.) [40][41][42][43][44][45] and growth of voids in the compression side of edge dislocations [46,47] is well-known for a long time. Recently, an evidence for the correlations between voids and other defects has been observed by Kozlov, Portnykh et al [48,49] in 20% cold-worked 16Cr-15Ni-2Mo-2Mn austenitic steel irradiated up to ~100 dpa in a BN-600 fast reactor in the temperature range 410 to 600ºC.…”

On the onset of void ordering in metals under neutron or heavy-ion irradiation. Philosophical Magazine, TaylorFrancis, 2010, 90 (13) Formation of void lattices is observed in a number of metals and alloys under high-energy particle bombardment. Here we derive the conditions for destabilisation of homogeneous void arrangement using an approach developed for the description of lane formation in pedestrian crowds. The model is based on the Foreman's mechanism of void alignment due to onedimensionally-migrating clusters of self-interstitial atoms. The results show that spatial correlations between voids should exist above some very small size, unless correlations with other defects prevail. It is shown that spatial correlations of voids with dislocations and secondphase precipitates should also evolve and provide a powerful driving force for further swelling.

“…Nevertheless, to our knowledge, P segregation on a cavity has only been reported in the case of void-precipitate association during neutron irradiation of austenitic stainless steels. Two types of phosphides Fe2P and Fe3P have been observed to be associated with cavities [59]. From the results of the current study, P was clearly segregating on cavities and was not observed to segregate on other defects neither from EDS nor APT analyses.…”
