Title: Non - destructive Analysis of FerromagneticMaterials by Means of Barkhausen Effect Methods Keywords: Magnetic noise voltage, Magneto-acoustic Abstract: The paper presents two modern methods based on the effect of Barkhausen and used for the study of specimens of construction steel and amorphous alloys. In particular, the methods discussed in the study are the method of magnetic noise and that of magneto-acoustic emission. The study deals with the effect of steel and amorphous alloys structure on the numerical characteristics of the magnetic noise (magnetic noise stress) and on those of the magnetoacoustic emission (mean quadratic stress of the acoustic emission). A possibility to apply those characteristics is outlined, i.e. one can use them when performing specific nondestructive control of constructional steels and amorphous alloys. It is proved that the signals of the magnetic noise stress and those of the magneto-acoustic emission depend on the magnitude of the structure of the studied construction steels and amorphous alloys.
