摘要：
The influence of modified layers formed during chemicothermal treatment and subsequent hydrogen saturation on the physicomechanical properties and acoustic emission (AE) of ring samples cut from a zirconium tube of the Zr-1% Nb alloy was investigated. It was established that the activity of low-amplitude AE signals of the oxidized alloy was on average three times greater than that of the untreated alloy, while of the high-amplitude signals it was less. Similar results were obtained after saturation with hydrogen. The character of the amplitude distribution of AE signals for an oxidized sample was decreasing, while for a vacuum-treated sample, it changed, in particular, the number of signals in the high-amplitude region increased significantly.
