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
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 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 ...

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 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 ...
