Abstract
The influence of neutron irradiation, from dose levels of 1•0 × 1015 to 0•97 × 1019 nvt, on the strain rate dependence of the flow stress in copper single crystals has been investigated at 77°K and 300°K. An analysis of this dependence shows that the activation energy for dislocations cutting obstacles introduced by the irradiation decreases with decreasing testing temperature and increasing neutron dose. Thus, a unique activation energy cannot be assigned to the process. This result is explained on the basis of variations in both the size and the density of the obstacles.Keywords
