Irradiation response of ODS Eurofer97 steel

Oxide dispersion strengthened (ODS) Eurofer97 steel (EU batch, 0.3wt.% of Y2O3 particles), produced by mechanical alloying followed by hot rolling, is irradiated in the High Flux Reactor in Petten, The Netherlands at three different irradiation temperatures (300, 450 and 550°C) up to nominal doses o...

Description
Summary:Oxide dispersion strengthened (ODS) Eurofer97 steel (EU batch, 0.3wt.% of Y2O3 particles), produced by mechanical alloying followed by hot rolling, is irradiated in the High Flux Reactor in Petten, The Netherlands at three different irradiation temperatures (300, 450 and 550°C) up to nominal doses of 1dpa and 3dpa. The effect of neutron irradiation on the mechanical properties of ODS Eurofer97 material is investigated. It is shown that the irradiation hardening of ODS Eurofer97 steel occurs at 300°C, whereas during irradiation at 450 and 550°C no changes in mechanical properties are observed compared to the unirradiated material. This effect is possibly a result of the annealing of the irradiation damage at temperatures higher than 300°C. The observed shifts in the Ductile to Brittle Transition Temperatures due to irradiation at different temperatures are discussed and compared with non-ODS Eurofer97 steel.
