Fundamental Mechanisms for Irradiation-Hardening and Embrittlement: A Review [PDF]
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.
