Ion irradiation offers a promising strategy to emulate the irradiation damage induced by
energetic neutrons. However, the characterization of the mechanical properties of ion …

Exposure of metals to neutron irradiation results in an increase in the yield strength and a
significant loss of ductility. Irradiation hardening is also closely related to the fracture …

Estimations of bulk hardness from nanoindentation are frequently subject to considerable
uncertainties due to indentation size effects (ISE), pileup effects, and potential influence of …

In this work, an integrated approach including experimental examinations and theoretical
modeling was employed to examine the temperature-dependent hardening of structural …

Orientation-dependent irradiation hardening phenomena in pure Zr have been studied, and
the corresponding mechanisms investigated based on the combined use of SEM, TEM, and …

In this work, a strain-gradient crystal plasticity theory with irradiation effect is proposed for the
surface nano-indentation of ion-irradiated FCC metals. In order to characterize the …

Abstract Development of irradiation hardening models attracts extensive attention in
designing nuclear materials. Dislocation dynamics (DD) method is a powerful tool in this …

It is very well known that tungsten is intrinsically brittle at room temperature, and the
characterization of its ductile properties by conventional mechanical tests is possible only …

In this study, the authors have applied the “Oblique Cross Section” or OCS method, for the
determination of the hardness changes in ion irradiated 316 stainless steel. The steel …

The effect of heavy ion or neutron irradiation on the plasticity of Zr-2.5 Nb pressure tube alloy
is investigated by a combination of nanoindentation and numerical modeling, with …
