On the analysis of stage I in the resistivity recovery of electron irradiated iron

The experimental results of Takaki et al. [1] on the stage I resistivity recovery of electron irradiated iron are analyzed using the analytical theory of diffusion annealing formulated by Simpson & Sossin [2] and Schroeder [3] taking into account the recent first-principles calculations of Fu et al. [4] regarding the mobility of interstitials. Excellent agreement between theory and experiment is obtained by a minimal set of adjustable parameters. The results show that the diffusion annealing equations can be successfully employed for the analysis of recovery experiments in iron. - Highlights: • The theory of diffusion annealing is employed for the analysis of the Stage I resistivity recovery in electron irradiated iron. • An accurate description of Frenkel pair recovery in stage I as a function of temperature and dose using the self-interstitial migration energy obtained recently by first-principle calculations. • The results show that the theory of diffusion annealing constitutes a suitable and powerful tool for the analysis of recovery experiments in iron.
