Fundamental Mechanisms for Irradiation-Hardening and Embrittlement: A Review
It has long been recognized that exposure to irradiation environments could dramatically degrade the mechanical properties of nuclear structural materials, i.e., irradiation-hardening and embrittlement.

Hydrogen embrittlement in irradiated steels [PDF]
Abstract Hydrogen charging conditions that completely embrittle an ultra-high strength steel have a negligible effect on 212-B pressure vessel steel in tensile and delayed failure tests, Much higher hydrogen charges reduce the notch tensile strength.

The neutron irradiation of Fe-based fusion and fission reactor materials leads to an increase in ductile-to-brittle transition temperature with a decrease in upper shelf energy. It is well known that Cu content has a strong influence on the embrittlement

Swelling and He-Embrittlement of Austenitic Stainless Steels and Ni-Alloys in Nuclear Reactors
Rate theory models have been developed for the swelling and He-embrittlement of austenitic stainless steels and Ni-alloys in nuclear reactors. The models illustrate how microstructure evolution during irradiation affects the rate of change of mechanical ...

Control of Irradiation Embrittlement in Molybdenum [PDF]
IRON, steel, and other body-centred cubic metals show an increase in ductile-brittle transition temperature as a result of neutron irradiation. In an attempt to elucidate the mechanism of this embrittlement for EN2 steel, Hull and Mogford1 studied the effect of neutron irradiation on the parameters σi and k y in the Petch relation:
