Kong et al. [7] studied the influence of Au ion irradiation damage on helium-implanted tungsten, used Orowan stress formula [8] to interpret the interaction between helium bubbles and irradiation defects in tungsten materials and found helium bubbles as impenetrable obstacles for the dislocation motion, and thought the density and size of helium bubbles were the key factors for hardening.
