Annealing of dislocation loops in neutron-irradiated copper investigated by positron annihilation

Creators

Description

Positron annihilation angular correlation measurements were carried out on neutron-irradiated copper as a function of annealing temperature. Two types of specimens were used: single crystals irradiated with fast neutrons, and 10B-doped polycrystalline samples irradiated with thermal neutrons. All irradiations were at approximately 3200K. A structure in the annealing curve, not previously observed by other techniques, indicates that between 460 and 6000K the dislocation loops present after irradiation dissociate and more effective positron trapping sites are formed.
