“…For example, there is not exhaustive explanation experimentally observed characteristic breaks and kinks (sudden changes of the derivative) in function of creep on dose and on temperature. [3][4][5][6][7][8] All these phenomena require future investigation, and its examination allows understanding specificity of creep under irradiation and the main mechanisms of creep development.…”

In the framework of the Orowan model, a theoretical approach is developed to explain the appearance of a break (local minimum and maximum) on a curve of creep rate dependence on temperature of materials under irradiation. The break is explained by competition of radiation and thermal defect fluxes to dislocations. At some temperature, the fluxes of interstitial atoms and vacancies become equal and compensate each other. Thus, the dislocations do not climb. Climb–glide mechanism does not contribute to the creep and the creep decreases. It is shown that the presence of sinks with different preference coefficients is necessary for the appearance of the break. Theoretical and experimental results are in good agreement.

“…It was also found that D-ferrite is formed without irradiation if nucleation sites are provided. 15 As mentioned in Reference 15, at the beginning of irradiation, a type of "primary" creep stage was observed for doses up to 3-5 dpa. The "primary" creep strain decreased in cold-worked steel materials with decreasing stress and decreasing irradiation temperature.…”
