Abstract

The effect of the gaseous medium composition during thermo-chemical treatment (TCT) on the mechanical properties and acoustic parameters of Zr-1%Nb zirconium alloy was studied. It is shown that TCT in oxygen-nitrogen contained gaseous media significantly increases the surface hardness and does not worsen the mechanical characteristics (including their plasticity) of zirconium alloy which is used as a material for case of fuel nuclear rod. It is established that TCT in different mediums also influences on acoustic parameters of the Zr-1%Nb alloy. Noticeable changes in the acoustic parameters observed at the initial stage of deformation are associated with the features of the destruction of a thin film formed on the zirconium alloy surface after TCT.
