Ion-irradiation hardening and microstructural evolution in F82H and ferritic alloys

Journal of Nuclear Materials, 2019
A reduced activation martensitic steel (F82H), Fe−8Cr ferrite model steel (8CrFS) and pure iron (Fe) were irradiated with 6.4 MeV Fe3+ ions at 300 °C to a displacement damage of 30 dpa at a nominal depth of 600 nm.

Precipitation and irradiation hardening in iron

Philosophical Magazine, 1961
Abstract Precipitation of carbon from α-iron during irradiation and thermal ageing has been studied using thin film electron transmission microscopy. During irradiation at 100°c precipitates formed with a density of 2 × 1014 cm−3 and saturated at 400 A diameter after 72 hours in a flux of 1·5 × 1011 neutron cm−3 sec−1 > 1 MeV.

Irradiation hardening of pure vanadium and vanadium alloys due to helium ion implantation and displacement damage

, 2020
Pure V and V–5Cr–5Ti were irradiated by He and high-energy heavy ions to various doses. Nanoindentation was used to characterize the hardness change induced by ion irradiation.

Surface hardening by proton irradiation

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1993
Abstract Ion implantation induced changes in the microhardness of semiconductor materials are systematically studied in AIII BV, AIIBVI and elemental semiconductors. The influences of different types of radiation defects and of implanted atoms are separately considered.

Irradiation hardening and microstructure evolution of ion-irradiated Zr-hydride

Journal of Nuclear Materials, 2011
Abstract 6.4 MeV Fe 3+ ion irradiation was applied to a e-Zr-hydride to clarify the relation between the hardening and the microstructure change of bulk Zr-hydrides under neutron irradiation. Irradiation hardening was measured by nano-indentation test.

Embrittlement of irradiated F82H in the absence of irradiation hardening

Journal of Nuclear Materials, 2009
Abstract Neutron irradiation of 7–12% Cr ferritic/martensitic steels below 425–450 °C produces microstructural defects and precipitation that cause an increase in yield stress. This irradiation hardening causes embrittlement, which is observed in a Charpy impact or fracture toughness test as an increase in the ductile-brittle transition temperature ...

Irradiation hardening in F82H irradiated at 573K in the HFIR

Journal of Nuclear Materials, 2011
Post-irradiation tensile tests were conducted on alloy F82H and variants of this steels irradiated at 573 K up to 19 dpa in the High Flux Isotope Reactor (HFIR) in Oak Ridge National Laboratory. Post-irradiation tensile and hardness tests revealed that the strength of F82H steeply increased below 5 dpa, and the total elongation decreased. The ductility
