Abstract
Magnetic traditional and adaptive methods as well as Barkhausen noise analysis were used for the testing of material degradation of plastically deformed high quality low-carbon steel. The dependences of the measured magnetic (coercive field, maximum permeability, optimum adapted permeability) and Barkhausen noise (RMS voltage, power spectrum) parameters are understood in terms of the increased dislocation density. The results are discussed in the context of potential application of magnetic testing methods for the indication of plastic deformation levels of ferromagnetic construction steel products.
