【 摘 要 】

Model samples of zirconium E635 alloy after rolling, annealing, quenching were subjected to reactor irradiation in BOR 60 up to a fluence ∼ 1026m-2. The Mössbauer studies data on the state of iron in the original samples previously subjected to rolling, annealing and quenching, and on the irradiated alloy samples are given. It is revealed that in the initial samples iron is in different intermetallic compounds, and also partly in the solid solution. During irradiation the iron atoms move from one type of intermetallic compounds to another one and in to the solid solution. Data on the relative content of iron in different phases and compounds are compared with the results of irradiation-induced growth strain measurements. The correlation between irradiation-induced grows and iron atoms redistribution in alloys is found.
