“…Thus, the common regularities analogous to those obtained in [21,22] are a decrease in the number of AE signals and in their energy with increasing degree of the BCD. In all the cases, there was also noted an increase in the median frequency of the AE spectra, which can be explained by an increase in the density of interfaces in the structure of the alloy, which is a con sequence of the low temperature deformation and subsequent warming up to room temperature.…”

“…In this regard, it is possible to suggest a hypothesis that during cyclic loading, various processes take place at different stages of loading, such as dislocation sliding, twinning, formation of stacking faults [6][7][8][9], formation and development of a microcrack. Provided that, various acoustic waves with specific energy-frequency characteristics are emitted at various stages of cycling.…”

Cyclic impact of external parameters on the structure, such as the daily change of temperature, change of operating parameters (pressure, temperature, volumes of loaded raw material) may lead to the brittle fracture of the equipment material with fast propagation of the main crack. In view of this, there is a need to use the nondestructive test methods which allow determining the critical level of damage accumulation. The article considers the pattern of change in properties as a result of low-cyclic loading by studying the parameters of acoustic signal. Changes in acoustic emission (AE) parameters were measured in the process of uniaxial tension of specimens with different degrees of accumulated damage. Upon processing of these AE parameters, stages of damage accumulation in cyclic fatigue were determined. Thus, is was determined that acoustic-emission diagnostics is sensitive to the said changes and may be used for assessment of the damage degree of 09G2S steel specimens.
