Fundamental Mechanisms for Irradiation-Hardening and Embrittlement: A Review
Metals, 2019 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.

The effect of high-pressure torsion on irradiation hardening of Eurofer-97 [PDF]
Nuclear Materials and Energy, 2023 We investigate the effect of nano-structuring by high-pressure torsion (HPT) on the irradiation performance of Eurofer-97. Material was deformed to shear strains from 0 to ∼230, and then exposed to Fe3+ irradiation doses of 0.01 and 0.1 displacements-per-

Irradiation hardening of pure tungsten exposed to neutron irradiation [PDF]
Journal of Nuclear Materials, 2016 Abstract Pure tungsten samples have been neutron irradiated in HFIR at 90–850 °C to 0.03–2.2 dpa. A dispersed barrier hardening model informed by the available microstructure data has been used to predict the hardness. Comparison of the model predictions and the measured Vickers hardness reveals the dominant hardening contribution at various ...

Evaluation of helium effect on ion-irradiation hardening in pure tungsten by nano-indentation method
Nuclear Materials and Energy, 2016 As-received and recrystallized pure tungsten (W) were irradiated with 6.4MeV Fe3+ up to 2dpa with or without He+ at 300°C, 500°C, 700°C and 1000°C respectively. Irradiation hardening was measured by the nano-indentation method.

Effect of cold work deformationon irradiation hardening of vanadium alloys
Nuclear Fusion, 2022 Vanadium alloys are regarded as promising candidate structural materials for the advanced blanket concept in fusion reactors due to their low activation, good high-temperature strength and, in particular, their compatibility with liquid lithium.
