Abstract
The amplitude of the pulses of the magnetoelastic acoustic emission signal is shown to be distributed according to the exponential law, which makes it possible to use its attenuation parameter as an informative one for the diagnostics of ferromagnetic objects. The dependences of the attenuation coefficients of the approximate exponents of the obtained amplitude distribu tions estimates on the applied load are constructed, which can be used as calibration curves for the diagnostics of residual stresses in long-term operation ferromagnetic objects.
