Abstract
Abstract High purity iron (residual resistance ratio ∼5000) and similar iron doped with carbon (15 at. ppm and 67 at.ppm) have been irradiated with 3 MeV electrons at low temperatures. The resistivity recovery of these specimens has been investigated in some detail. The results allow the following interpretations: Two recovery stages, Stage I E (120–140 K) and Stage III (220–278 K), are related to free migration of elementary atomic defects. Other, secondary recovery stages related to long-range defect migration, appeared at 164–185 K, and at 340–360 K, the latter is due to the motion of interstitial carbon atoms. The Stage I E defect and the Stage III defect, both react with carbon. The binding enthalpy for the I E defect-carbon complex is 0.11 eV, for the Stage III defect-carbon ∼1.1 eV. The specific defect resistivity of the Stage II defect-carbon complex is distinctly lower than that of the Stage I E defect-carbon complex. We ascribe the Stage I E defect as an interstitial atom and the Stage III defec...
