The experimental investigations were carried out in order to quantitatively determine a change of parameters of signals of magnetoelastic acoustic emission under effect of structural transformations and level of hydrogenation of ferromagnetic materials. It is shown that application of a phenomenon of magnetoelastic acoustic emission can make a basis for development of the new high-sensitive non-destructive technologies for detection of hydrogen taken by material during long-term operation of structures. 7 Ref., 9 Fig.
Keywords: non-destructive testing technologies, metallic structures, hydrogen-containing media, magnetoelastic emission, parameters of signals, increase of sensitivity
