“…Recently, magnetoacoustic emission (MAE) techniques have received great attention in NDT for their high sensitivity to properties of ferromagnetic materials [13]. MAE refers to the acoustic emission generated during the magnetization of ferromagnetic materials [14,15], and it has been used to evaluate the mechanical properties of ferromagnetic materials, such as surface hardness [16,17], elastic deformation [18,19], plastic deformation [20][21][22], creep damage [23,24], and fatigue degree [25,26]. Due to the detection ability and generation mechanism of MAE being closely related, experiments have been widely performed to speculate on the generation mechanism of MAE.…”

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.

“…In works [1][2][3][4][5][6] and a number of other works it was shown that the determination of the set of magnetic and magnetoacoustic characteristics makes it possible to reliably assess the structural-phase state, strength properties, as well as the stresses present in ferromagnetic materials. This possibility is due to the following reasons: 1) the interaction of moving domain boundaries with defects in the crystal structure and inhomogeneous stresses; 2) magnetoelastic effect -a change in magnetization and a change in the dynamics of 90degree domain walls when elastic stresses are applied to a ferromagnet; 3) magnetostrictive effect -a local change in the size of the ferromagnet due to the rearrangement of the domain structure.…”

The change in the magnetic and acoustic properties of nickel as a result of cold deformation and subsequent annealing is investigated. It was found that annealing leads to very significant changes in the magnetic and acoustic properties of nickel. The coercive force decreases 50 times with an increase in the annealing temperature to 800 °C. The Rayleigh coefficient, which characterizes the mobility of domain walls, monotonically increases by a factor of 20 over the entire investigated range of annealing temperatures. The greatest changes in the velocity and damping of longitudinal ultrasonic vibrations occur in the range of recrystallization temperatures. It is shown that to diagnose the structure and magnitude of residual stresses in nickel, it is advisable to determine its magnetic and acoustic parameters.
