Abstract
An overview of the prospects for the development of nuclear technologies and the conclusion of the relevant
requirements for advanced structural materials, their classification and features were described. In order to
obtain a bar with a modified radiation-resistant outer layer, an experiment on radial-shear rolling of the Zr-1%
Nb alloy in conditions favorable for the UFG structure formation was conducted. In the process of radial-shear
rolling of round bars along the route 37 mm → 20 mm in diameters with a total deformation
of ≈ 70 %, a microstructure of submicron size was obtained. The nature of the microstructure is equiaxed
with mainly high-angle boundaries and large crystallographic misorientation of the grains that is the most
promising from the point of view of radiation resistance.
