Abstract
The recovery behavior of defects in irradiated titanium has been studied. The changes in electrical resistivity and microhardness of the samples irradiated to a fast neutron fluence of 1.3 × 1020 n/cm2 were measured after annealing at various temperatures. The activation energy for the recovery was found to be 0.97 eV, which was somewhat smaller than that reported for the self-diffusion of titanium (1.241.27 eV). Transmis-sion electron microscopy was applied out to determine the relation between the recovery process and changes in the microscopic structure. It was revealed that the recovery of hardness coincides with the disappearance of black spots observed in electron micrographs of irradiated titanium samples.
