“…[1][2][3]. The mechanical properties of metallic materials could be dramatically degraded by these defects, which is termed as the irradiation effects on mechanical properties including irradiation hardening, embrittlement, creep, and so on [4][5][6]. Hence, a deep understanding of irradiation effects is vital to the development of advanced structural materials for nuclear reactors.…”

Ion irradiation, combined with nanoindentation, has long been recognized as an effective way to study effects of irradiation on the mechanical properties of metallic materials. In this research, hardening and creep of ion irradiated Chinese low activation martensitic (CLAM) steel are investigated by nanoindentation. Firstly, it is demonstrated that ion irradiation results in the increase of hardness, because irradiation-induced defects impede the glide of dislocations. Secondly, the unirradiated CLAM steel shows indentation creep size effect (ICSE) that the indentation creep strain decreases with the applied load, and ICSE is found to be associated with the variations of geometrical necessary dislocations (GNDs) density. However, ion irradiation results in the alleviation of ICSE due to the irradiation hardening. Thirdly, ion irradiation accelerates nanoindentation creep due to the large numbers of irradiation-induced vacancies whose diffusion controls creep deformation. Meanwhile, owing to the annihilation of vacancies, ion irradiation has a significant influence on the primary creep while only negligible influence has been observed for the steady-state creep.

“…For this purpose, in-pile creep capsules with uni-axial creep specimens for irradiating under different neutron spectra were developed for JMTR testing. Figure 2-12 13 shows a schematic diagram of one of the creep irradiation capsules (94M-2A). Different levels of stress can be applied to two creep specimens using bellows pressurized by helium gas.…”

“…The effects of irradiation on creep properties of various materials has been investigated by in-pile or/and post-irradiated creep test conducted using several methods; including MTRs, fission reactors, cyclotron or other setups. [42][43][44][45][46][47][48] Irradiation creep has been extensively investigated to provide data that can be used for component analysis.…”
