MAGNETIC EVALUATION OF THE STRUCTURAL AND PHASE CHANGES IN INDIVIDUAL LAYERS OF MULTILAYER PRODUCTS

Magnetic hysteresis loop distortion occurring during the magnetization reversal of multilayer ferromagnets can be used to evaluate the structural changes and phase transformations in composite product layers with different properties. For practical application, it is proposed either to record the differential magnetic permeability of each layer or to measure the electromotive force in the coil encompassing a product under magnetization reversal by linear alternating current.

Keywords: composite material, surface hardening, structure, phase, hysteresis loop, differential magnetic permeability, field of differential magnetic permeability, coercive force
