Materials subjected to high dose irradiation by energetic particles often experience severe
damage in the form of drastic increase of defect density, and significant degradation of their …

Helium (He) bubbles are typical radiation defects in structural materials in nuclear reactors
after high dose energetic particle irradiation. In the past decades, extensive studies have …

It has long been recognized that exposure to irradiation environments could dramatically
degrade the mechanical properties of nuclear structural materials, ie, irradiation-hardening …

Nanocrystalline materials are known to possess excellent radiation resistance due to high
fraction of grain boundaries that act as defect sinks, provided they are microstructurally …

RAFM steels such as Eurofer-97 and Eurofer-ODS are potential structural materials for future
fusion reactors. In order to study their resistance to the high energy neutrons they will be …

A reduced activation ferritic/martensitic steel, Eurofer97, was neutron irradiated in the vicinity
of 300° C in the High Flux Isotope Reactor (HFIR) up to 72 dpa. Advanced analytical …

The effect of Zr in the range of 0–∼ 1.36 wt.% on the microstructure and mechanical
properties of 12Cr ferritic/martensitic steels was investigated. The steels were prepared by …

Ferritic/martensitic (FM) steels are the one of major classes of materials included in the SINQ
Target Irradiation Program performed at the Paul Scherrer Institute. A large matrix of FM …

Specimens of martensitic steel F82H were irradiated to doses ranging from 10.7 dpa/850
appm He to 19.6 dpa/1740 appm He at temperatures between 165 and 305° C in the …

The irradiation resistance of CLF-1 steel was investigated by using He ion irradiation with an
energy of 300 keV. After the irradiation, the structure of CLF-1 steel mainly remained …
