Heat treatment effect on the carbon distribution in zirconium and alloy Zr + 2.5% Nb

It is shown that annealing of zirconium and alloy Zr + 2.5%Nb in vacuum 10-2-10-3 Pa at 900-1200 deg C is accompanied by formation on their surfaces of zirconium oxycarbide (ZO) layer. It is established also that the ZO formation is conditioned by impurity carbon as a result of its diffusion to the...

Zusammenfassung:It is shown that annealing of zirconium and alloy Zr + 2.5%Nb in vacuum 10-2-10-3 Pa at 900-1200 deg C is accompanied by formation on their surfaces of zirconium oxycarbide (ZO) layer. It is established also that the ZO formation is conditioned by impurity carbon as a result of its diffusion to the sample surface.
