Abstract
Methods of analytical electron microscopy were used to study the micro structures of ferritic-martensitic steels irradiated with fast neutron s (some of the specimens were examined after intermediate thermal anne aling and reirradiation). It was found that neutron irradiation in the temperature range for low temperature radiation embrittlement (370-38 0 degrees C) leads to the formation of fine precipitates and a radiati on-induced dislocation structure. The Cr content is found to have an i nfluence on phase composition under irradiation: carbonitrides of type M(2)X formed in 9% steels and Cr-rich alpha'-phase in 13% steels.
