The paper experimentally shows the possibility of using local measurements of the magnetic properties (coercive force and Barkhausen noise parameters) of steel products, as well as the parameters of magnetic leakage field of these objects, for the early-stage detection (before macrocracking) of potential fracture sites in the form of single and multiple zones of plastic strain localization. © 2022 The Authors.

Introduction Plastic deformation in materials is not uniform throughout the volume, but only within separate areas called plastic strain localization zones (PSLZ), see in Honeycombe (1968), Pavlov (1962), Smirnov et al. (1987). This localization of macroscopic strain is one of the main features of the deformation of materials with very different structures. It is in PSLZs that material damage accumulates; they are stress concentrators and, consequently, The paper experimentally shows the possibility of using local measurements of the magnetic properties (coercive force and Barkh usen noise parameters) of st el produc s, as well as the par meters of magn tic leakage field of these obj cts, for the early-stag detection (before macrocracking) of potentia fracture sites in the orm of s ngle and multiple zones f pla tic strain localization. © 2022 The Authors.
