Abstract

The paper investigates the effect of hydrogenation towards the concentration of 0.33 wt % on the structural and phase state and the deformation process development during tension of the ultrafine-grained Zr-1 wt % Nb alloy (hereinafter Zr-1Nb) at the temperature range of 293-973 K. Hydrogen presence in the alloy in solid solution and hydride precipitates are found that results in an increase of its strength and plastic characteristics at room temperature. At elevated temperatures hydride dissolution activates dislocation motion that leads to strength characteristics reduction and to rise of deformation-to-failure.
