Atomic Defects in Metals · Re

This chapter discusses isochronal annealing of electrical resistivity of rhenium (Re) after irradiations with e^-, α-particles, thermal neutrons and fast neutrons and after plastic deformation. The annealing stage I has been observed after all types of irradiation. A dose dependent temperature shift of stage I_E has been observed after α-particle irradiation, but could not be observed by the same group of authors after e^--irradiation. The dose dependence of stage III is demonstrated for Re. The activation energy has been observed after irradiation and plastic deformation. The properties of Frenkel defects (FD), self-interstitial atoms (SIA), and vacancies (V) in Re are tabulated. Complete annealing of defect clusters is supposed to be observed at T ≈ 1100 K after n-irradiation, however, some additional resistivity is remaining due to transmutation elements.
