High-purity iron specimens varying in chemical composition were exposed to neutron radiations to study resultant changes in mechanical properties. Metallurgical investigations revealed that important property changes can be attributed to initial chemical composition, as well as accumulated neutron exposure. It was further discovered that structural responses to strain-aging and damage-recovery treatments vary with irradiation. Reversals in some property changes in the high exposure range revealed that net property changes in irradiated iron cannot be explained exclusively in terms of damage accumulation which approaches saturation. Considerations are given to damage mechanisms, the redistribution of impurities, the causes of gross embrittlement, and the nature of initial plastic yielding. (auth)
