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.

Evaluation of helium effect on ion-irradiation hardening in pure tungsten by nano-indentation method [PDF]
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.

Irradiation Hardening Behavior of He-Irradiated V–Cr–Ti Alloys with Low Ti Addition
Quantum Beam Science, 2020 A set of V–(4–8)Cr–(0–4)Ti alloys was fabricated to survey an optimum composition to reduce the radioactivity of V–Cr–Ti alloys. These alloys were subjected to nano-indenter tests before and after 2-MeV He-ion irradiation at 500 °C and 700 °C with 0.5 ...

Irradiation damage and hardening in pure Zr and Zr-Nb alloys at 573 K from self-ion irradiation
Materials & Design, 2019 Zr-ion irradiation was performed on pure Zr, Zr-2.5Nb, and Zr-5Nb to a dose of 0.5 or 5 dpa at 573 K. The irradiation induced defects, alloying element redistribution, precipitation, and hardening were analyzed by Transmission Electron Microscopy and ...

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-

Model for the hardness-depth relationships of ion-irradiated nanocrystalline metals
Journal of Materials Research and Technology, 2023 In this work, a mechanistic model is proposed for ion-irradiated nanocrystalline (NC) metals to characterize the evolution of hardness as a function of the indentation depth at room temperature and under quasi-static loading condition. At the grain level,
