Abstract

We analyze the characteristics of acoustic emission (AE) observed in the process of mechanical testing of hydrogenated and hydrogen-free specimens of thermal power equipment in uniaxial tension and three-point bending. It is shown that, in both cases, AE signals in hydrogenated specimens appear at earlier stages of loading than in hydrogen-free specimens. We suggest the use of this phenomenon in detecting hydrogen-induced damage to steel. It is discovered that the deposition of scale on the surface of pipes makes the interpretation of received AE information much more complicated.
