Investigation of microstructural evolution under neutron irradiation in Eurofer97 steel by means of small-angle neutron scattering

Evolution of microstructure in advanced ferritic-martensitic steels under irradiation: the origin of low temperature radiation embrittlement

“…The most complicated problem is to investigate their radiation resistance, especially at high displacement damage doses. Specimens of the Eurofer97 irradiated in High Flux Reactor (HFR, Petten, Netherlands) to doses of 2.5, 8.4, and 16.3 dpa have been studied in [12][13][14][15]. The effect of irradiation up to 32 dpa has been analyzed in a BOR 60 reactor (Dimitrovgrad) in the framework of ARBOR 1 project [8,16].…”

The microstructure of neutron-irradiated Fe–Cr alloys: A small-angle neutron scattering study

“…Special advantages of SANS are related to the capability of averaging over both macroscopic volumes of some 10 mm 3 and statistically reliable numbers of features of the order of 10 6 . A number of SANS studies was performed for several neutron-irradiated ferritic-martensitic high-Cr steels [5,6]. Depending on neutron fluence and composition these authors found indications for nanovoids, carbides and the Cr-rich a 0 -phase.…”

Recent applications of small-angle neutron scattering in the characterization of irradiated steels for nuclear technologies

“…The Eurofer-97 sample (9 Cr, 1 W, 0.2 V, 0.1 C wt.%) was irradiated at 250°C and 300°C at the HFR-Petten up to target dose levels of 2.5, 8.4 and 16.5 dpa [16][17][18][19][20]. The results of SANS measurements carried out on 2.5 dpa and 8.4 dpa irradiated Eurofer are reported in Refs.…”
