Influence of thermochemical treatment on properties of tubes from Zr-1%Nb alloy
The influence of treatment in the controlled oxygen- and nitrogen-containing gas medium on the mass increment and properties of the subsurface layers of samples-rings, cut out of the fuel cladding tubes from Zr-1%Nb, has been established experimentally. Differences in the saturation of internal an...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The influence of treatment in the controlled oxygen- and nitrogen-containing gas medium on the mass increment
and properties of the subsurface layers of samples-rings, cut out of the fuel cladding tubes from Zr-1%Nb, has been
established experimentally. Differences in the saturation of internal and external surfaces of zirconium tubes were
described. Results of examining the hardness of external and internal subsurface layers of the ring-samples after
oxidizing and nitriding are presented. It has been established experimentally that prolonged isothermal annealing at
750 ºC in the oxygen medium can lead to the initiation of a crack on the inner surface of zirconium tubes. |
