Effect of Plastic Deformation on the Low Temperature Recovery after Neutron Irradiation

概要

The effect of deformation before and after fast neutron irradiation at about5 K on the recovery spectra of Ag, Ni and Pt is studied by means of measurementsof the residual resistivity. An amount of the stage I recovery is reduced by about5N8 % by deformation of pre-irradiated specimcn when an amount of the defor-nation is only 2--?3 '% in the surface shear strain in twisting. The amount of thereduction in stage I is comparable to the amount of an enhancement of therecovery above the stage II. [11 PI, overlapping on this effect, about 2O'3 of thestage I defects shift to a little higher temperature in their a?tnealing. This lattereffect is also observed on Pi when the deformation is made before irradiation. The present results, together with the previous results on Cu, AN and Au,are discussed in relation with the existing models for the recovery of radiationinduced point defects.
