摘要

本文介绍了通过改性Zr-1%Nb合金近表层来改善燃料棒性能的数据。在受控的气体环境下，根据近表层的弥漫性氧饱和度，采用热化学处理(TCT)进行改性。结果表明:与初始状态相比，TCT没有降低Zr-1%Nb合金的力学性能，但在某些情况下会提高其力学性能。研究了不同热处理制度对Zr-1%Nb合金空气氧化特性和氢饱和度的影响。结果表明，在550℃的空气中氧化100 h时，TCT的最佳处理方案可以减少重量增加，并防止Zr-1%Nb合金被氢饱和。结果表明，TCT是一种很有前途的提高Zr-1%Nb合金燃料棒性能的方法。

EFFECT OF THERMOCHEMICAL TREATMENT ON THE Zr-1%Nb ALLOY CHARACTERISTICS

Data on improving the characteristics of fuel rods made of the Zr-1%Nb alloy by modifying the near-surface layer are presented. For modification, thermochemical treatment (TCT) was used in a controlled gas environment based on the diffuse oxygen saturation of the near-surface layer. It was established that TCT does not reduce the mechanical characteristics of the Zr-1%Nb alloy compared to ones in the initial state, but in some cases increases its. The influence of different regimes of TCT on the features of oxidation in air and hydrogen saturation of the Zr-1%Nb alloy was considered. It was shown that the optimal regime of TCT provides a reduction in weight gain during oxidation at a temperature of 550 °C in the air for 100 h, and prevents saturation with hydrogen of Zr-1%Nb alloy. It was concluded that the TCT is a promising method for improving the performance of Zr-1%Nb alloy fuel rods.
