High-temperature annealing stages in irradiated imperfect crystals

The effect of neutron irradiation on the structure of crystals with different dislocation densities and types of crystal lattice and on subsequent high‐temperature annealing is studied. The extent of this effect is determined by the substructure of irradiated material. The processes responsible for stage V and VI annealing of radiation‐induced defects are investigated by quantitative X‐ray diffraction topography and two‐crystal spectrometer technique. A retarding effect of neutron irradiation on all the stages of recrystallization is established enabling the temperature range of application of hardened metal and alloys to be shifted to higher temperatures.
