摘要：
This paper presents experimental data of the study of the influence of Fe alloying on the changes of the structure of the Zr-1%Nb alloy and evolution of the structure of this alloy under ion irradiation. It is shown that small additions of Fe to the Zr-1%Nb alloy lead to the change its structure due to the formation of Laves phase precipitates. Influence of ions Ar2+ irradiation on parameters of dislocation loops in alloy Zr1%Nb with Fe content 0.012 ... 0.192 wt.% is studied by methods of transmission electron microscopy. Irradiations was carried out by Ar2+ ions (accelerator ESU-2) with energy 1.4 MeV, at temperature T = 390 degrees C. Dependence of density and size of dislocations on Fe content and on irradiation dose are obtained.
