The effects of crystallographic anisotropy and the domain structure on the parameters of the double electromagnetic-acoustic transformation (EMAT) are investigated in Fe-3% Si single crystals. A relationship is found between the magnitude of an EMAT signal and the quantity and activity of 90° domain boundaries, which determine the magnetostriction deformation of a crystal lattice. This relationship can be used as a basis for a method of nondestructive testing of elastic moduli and their related parameters. The possibility of determining the elastic moduli of ferromagnetic materials by parameters of the EMAT signal is shown.
