“…A similar trend of changes is observed in [13]. In [30], Fe-2%Si alloy is investigated using an enveloping coil, which allows the assumption that the magnetization direction is the same as the direction of the load. It is found that a rise in plastic strain involves a rise in the integrals of U b voltage.…”

Measurements are carried out of the Barkhausen noise (BN) and hardness on specimens where changes in hardness were obtained due to strain hardening (S235 and DC01 steels) and due to thermochemical treatment (AMS 6414 steel). A method is presented of processing the recorded BN signal to extract diagnostic information. The BN number of events is selected as the signal characteristic property to develop relevant correlations. A new methodology is presented for the development of correlations between the Barkhausen noise number of events and hardness. A possibility is indicated of developing correlations with a high R2 determination coefficient. The method limitations are specified.

“…Several studies have been published [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] to describe the possibility of applying non-destructive magnetic techniques on the study of changes in microstructure, grain size, stress state and plastic deformation in cold-rolled Non-Oriented Electrical Steels (NOES). Simulations of the performance of magnetic non-destructive techniques in order to investigate the microstructural changes in welded NOES have been carried out in the past [43,44].…”

“…Generally, the plastic deformation causes the change of the dislocation density, this change affects the pinning strength of domain walls and consequently their movement. 7 B. High temperature measurement Figure 5 shows the measurement results in high temperature condition between 20 and 140 C. As shown in the figure, the magnetic properties exhibit a certain decrease with an increase of the temperature, and the undeformed part shows more obvious changes compared with the deformed part.…”

Appl. Phys. This paper introduces a new measurement setup for extraction of the local magnetic properties. With the help of finite element method simulations, modifications are made on the previous double-C-yoke method. Small dimension measuring coils are applied in the stray field produced by the magnetic circuit to evaluate the local magnetic properties of the specified part of the specimen. Through the measurements with the plastically deformed materials at different temperatures, it indicates that the magnetic properties of soft magnetic materials are quite sensitive to plastic straining. After high-temperature thermal treatment on the plastically deformed specimen, the local magnetic properties exhibit an obvious recovery.
