“…It depends on many uncontrollable experimental factors: the yoke-sample and the BN coil lift-offs, mistakes of the Hall array calibration and its angle positioning, etc [15]. It should also be taken into account that this mistake additionally includes the technological deviations of steel microstructure, which can provide comparable result deviations [29]. We neglect the systematic error of our laboratory devices, whose maximum level is expected to be about 0.5-1%.…”

Abstract. Macroscopic hysteresis and local Barkhausen noise techniques were used for the comprehensive magnetic investigation of structural low-carbon steel subjected to uniaxial plastic tension. Scattering of the measured magnetic parameters was substantial within the Lüders band region with stabilization at higher strains. Compressive residual stresses in the deformation direction formed a hard magnetization axis with intriguing two-phase remagnetization. The magnetic parameters had highest sensitivity to strain in this direction. They changed as cos 2 with rotation to the perpendicular easy magnetization axis, where the magnetic sensitivity was lowest. The relation between the deformed steel microstructure (dislocation and residual stress patterns) and the obtained magnetic behaviour is interpreted. Applicability of the examined techniques for the non-destructive characterization of steel degradation is discussed.

“…As described in review articles by Korzunin et al, 1,2 consequential to the many processing steps used in the fabrication of electrical steels, the many factors needing careful control during each step, and to the batch size required for economical production, these materials typically exhibit significant variations in composition, microstructure, residual stress and gauge. Such variations exist between rolls, between sheets taken from different locations within one roll, between samples taken from one sheet and even locally on one sample.…”

Variations in the longitudinal drag force on a magnet close to a slowly moving strip sample of electrical steel are shown to provide sensitive, nondestructive indications of local inhomogeneity in the permeability, dimensions, and hysteresis loss of the sample. Measurements of both grain-oriented and nonoriented electrical steels showed drag force variations of unexpectedly large amplitude for movements of just a few millimeters, often with quasiperiodic features. Hysteresis variations were smaller and less drastic.
