“…The presence of ductile intergranular component indicates the progress of segregation processes in the steel under irradiation and the occurrence of precipitates with phosphorus segregation on their interface boundaries in locations of former austenite grains. It was shown earlier [1,2] that ductile intergranular fracture mode, which realizes in the case, when grain boundaries are decorated with precipitates with phosphorus segregation on them, that decrease cohesive strength of these boundaries, is an indirect confirmation of segregation presence on radiation-induced precipitates located on the former austenite grain boundaries. In this case the surface of ductile fracture, that envelopes interface boundaries of segregation, follows grain boundaries of the material.…”

“…In the case of Russian steels affected by these aspects, some data may be found in the literature. 9,10 More information is required to understand the reason for the re-embrittlement of Ł Correspondence to: Dr P. Pareige these materials. In addition, it appears that a comprehensive understanding of the mechanisms responsible for primary embrittlement under primary irradiation cannot be achieved without structural studies applied to the same materials that have undergone recovery annealing and re-irradiation.…”
