Characterization of radiation induced defects in EUROFER 97 after neutron irradiation

Tensile behavior of RAFM alloys after neutron irradiation of up to 16.3 dpa between 250 and 450 °C

“…6. The concentration of dislocation loops was 4 Â 10 21 cm À3 after irradiation at 300°C, Klimenkov et al [17]. F82H mod.…”

Helium influence on the microstructure and swelling of 9%Cr ferritic steel after neutron irradiation to 16.3 dpa

“…Additionally, the swelling was calculated for EUROFER 97 without boron based on results published in Ref. [9]. The total density of dislocation loops/point defects for specimens irradiated at 523 K was calculated based on the image with (110)g vector and then calculated as N = 2/3n 110 .…”

“…The formation of bubbles with sizes down to 10 nm and a sharp, Gauss-like size distribution with a maximum around 5 nm were observed in alloy 3 (Fig. 5c), whereas no cavities were detected in EUROFER 97 [9].…”

“…In the EUROFER 97 specimen irradiated at 673 K, individual cavities were detected, which contribute to negligible, but measurable swelling [9]. In the alloys 1 and 2 irradiated at 723 K, no formation of faceted voids was detected, the He-filled bubbles were mainly located in dislocations, precipitates, or grain boundaries.…”

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].…”
