Plasticization of neutron-irradiated LiF crystals upon thermal stimulation of a single-system dislocation glide

It has been shown that post-radiation annealing of LiF crystals irradiated by high neutron fluences (10 15 –10 18 neutrons/cm 2 ) at comparative low temperatures (300–400°C) creates optimal conditions for single-system dislocation glide, which favors a complete recovery of the plasticity with conser...

Zusammenfassung:It has been shown that post-radiation annealing of LiF crystals irradiated by high neutron fluences (10 15 –10 18 neutrons/cm 2 ) at comparative low temperatures (300–400°C) creates optimal conditions for single-system dislocation glide, which favors a complete recovery of the plasticity with conservation of a significant fraction of radiation hardening.
