摘要：
The acoustic emission method for estimating damage to specimens made of thermally resistant steel is described as applied in air and in a gaseous hydrogen medium. Acoustic diagrams (AD) of steel cracking and their interpretation are presented. It is shown that thermal cycling of the steel in air and in a hydrogen medium leads to an increase in bulk damage to the steel. It is shown that the exploited material is more subject to micro- and macrocracking under the influence of temperature and the working environment.
