Dose rate effects in nickel-ion-irradiated nickel

Effects of oversized element Sn on diffusion of interstitial clusters in Ni irradiated by ions and neutrons

“…In order to extrapolate experimental data obtained by ion irradiation to fusion neutron conditions, it is necessary to know the correlation between two radiation environments. The effect of damage rate on microstructural evolution has been studied experimentally and theoretically [1][2][3][4][5][6][7][8]. For example, the temperature of the swelling peak increases with increasing damage rate for void formation.…”

Langevin model for real-time Brownian dynamics of interacting nanodefects in irradiated metals

“…Indeed, there is experimental evidence for the effect of dose rate on microstructural evolution of irradiated materials. [23][24][25] In situ electron microscope observations show that simultaneous, as opposed to sequential, production of mobile defects at high irradiation dose rates results in microstructural evolution that is influenced by the "collective" dynamical events involving correlated motion of several defects, leading to the formation of defect rafts, coalescence of defects, and the eventual self-organization and spatial ordering of defects. All these phenomena are routinely seen in in situ electron microscope experiments, [1][2][3][4][5][6] suggesting that interaction between radiation defects does play a significant part in the dynamics of microstructural evolution in the limit of high irradiation dose rates.…”

In service design by simulations

“…Comparison between theory predictions and experimental data is shown in Figure (??). The data include Ni+ ion [19,6,37]- [38], fission neutron [32,40], and proton [14,13] irradiations. The filled symbols denote conditions where defect cluster wall formation was observed.…”
