“…Therefore, the magnetic properties of samples 2, 3, and 4 are lower than those of sample 1. Based on our previous study [ 34 ], the pearlite (martensite) content and pearlite (martensite) grain area in the sample are significant effect on the micro-magnetic NDT signal. And the microstructure characteristics of the samples were obtained using image processing techniques as shown in Table 2 [ 34 ].…”

“…The crystal structure affects not only the magnetic domain structure and motion properties, but also the mechanical properties. Compared with ferrite, granular pearlite has a different crystal structure and is harder, less plastic, and more difficult to deform [ 34 ]. Under stresses of 5–80 MPa, ferrite in sample 2 was not deformed, so it showed more consistent variation.…”

“…Image gray level layering technique based on Python was used for magnetic domain feature extraction [ 34 ]. First, the image is binarized by choosing a suitable threshold value, and then the area share of the target pixels is extracted as the area share of the difficult-to-magnetize magnetic domains ( Figure 14 ) [ 34 ] The quantitative results are shown in Table 3 .…”

Both microstructure and stress affect the structure and kinematic properties of magnetic domains. In fact, microstructural and stress variations often coexist. However, the coupling of microstructure and stress on magnetic domains is seldom considered in the evaluation of microstructural characteristics. In this investigation, Magnetic incremental permeability (MIP) and magnetic Barkhausen noise (MBN) techniques are used to study the coupling effect of characteristic microstructure and stress on the reversible and irreversible motions of magnetic domains, and the quantitative relationship between microstructure and magnetic domain characteristics is established. Considering the coupling effect of microstructure and stress on magnetic domains, a patterned characterization method of microstructure and stress is innovatively proposed. Pattern recognition based on the Multi-layer Perceptron (MLP) model is realized for microstructure and stress with an accuracy rate higher than 97%. The results show that the pattern recognition accuracy of magnetic domain features and micro-magnetic features simultaneously as input parameters is higher than that of micro-magnetic features alone as input parameters.

Magnetoacoustic emission (MAE) holds great promise for evaluating the mechanical properties of ferromagnetic materials. To refine the problems of the current theoretical and numerical models of MAE, a theoretical MAE model that considers the microscopic dependence of the hysteresis properties is proposed in this paper. The microstructure (dislocation density and grain size) and the correlation of MAE jumps are considered and incorporated into the model. Then, the influences of magnetization parameters and microstructure parameters on the envelope of the MAE signal are analyzed by the proposed theoretical model. The proposed theoretical model is then fully evaluated by simulations and experiments. The MAE experiments are conducted on ferromagnetic specimens with different hardnesses, and the MAE signals with different hardnesses are simulated by inverting the basic parameters of the MAE model with the genetic algorithm. Further, the crucial hysteresis parameters of the specimens are calculated using the results of microscopic measurements and the calculated parameters agree well with inversion results from experimental signals. The results demonstrate that the proposed theoretical model is valid for the MAE signal simulation. The trends of different hardnesses can be predicted by the MAE simulation signals. Moreover, the model can be used for theoretical analysis of the microscopic dependence of the MAE signal.
