“…Even though this modeling approach can be successful for some configurations, it does not give a general description of the magneto-elastic behavior and can be inaccurate in some cases (Aydin et al, 2020). Another modeling approach is the multiscale approach, where local free energy at the domain scale is considered to get the macroscopic magneto-elastic behavior (Fagan et al, 2022). Another solution is obtained by defining a Helmholtz free energy density, that is, a function of five scalar invariants of the magneto-mechanical loading (Clemente et al, 2017).…”

The increasing demand for autonomous devices has made the concept of energy harvesting a significant industrial and academic point of interest. In this domain, an ideal magnetostrictive material for converting mechanical vibrations into electrical energy in a cost-effective way (i.e. competing with the price of primary batteries) remains to be determined. Iron-Cobalt-Vanadium (Permendur, Co49-Fe49-V2) is a promising candidate: it is a soft ferromagnetic material with high magnetization saturation, high magnetostrictive coefficients, low price, and good availability. In this study, the experimental magnetic characterization and simulation of Permendur sheets under tensile stress were performed, and their energy conversion capabilities were assessed. The conversion ability was predicted using thermodynamic Ericsson cycles from reconstructed anhysteretic curves. A maximum of 10.45 mJ cm−3 energy density was obtained under a tensile stress of 480 MPa and a magnetic excitation of 5.5 kA m−1. Then, an additional estimation was proposed to account for the hysteresis losses. For this, major hysteresis loops at different stress levels were considered, yielding an energy density of 3.52 mJ cm−3. Finally, experimental Ericsson cycles were performed to prove the feasibility of the conversion and corroborate the energy level predictions.

“…The domain number is vast, the wall motions can be assimilated to a stochastic process, and the MBN raw signal is erratic and not reproducible. For repeatable results, time average indicators are always preferred for the MBN analysis, including the Magnetic Barkhausen Noise energy (MBN energy ) described below [ 21 , 22 , 29 ]:…”

“…Sometimes the magnetization mechanisms are triggered simultaneously, and their answers overlap, leading to even more complex interpretations. Still, a specific sensitivity characterizes every magnetization mechanism [ 20 , 21 ]. An ideal way to monitor GBs is to develop an experimental situation where the most responsive magnetization mechanism can be isolated and easily monitored.…”

Grinding thermal damages, commonly called grinding burns occur when the grinding energy generates too much heat. Grinding burns modify the local hardness and can be a source of internal stress. Grinding burns will shorten the fatigue life of steel components and lead to severe failures. A typical way to detect grinding burns is the so-called nital etching method. This chemical technique is efficient but polluting. Methods based on the magnetization mechanisms are the alternative studied in this work. For this, two sets of structural steel specimens (18NiCr5-4 and X38Cr-Mo16-Tr) were metallurgically treated to induce increasing grinding burn levels. Hardness and surface stress pre-characterizations provided the study with mechanical data. Then, multiple magnetic responses (magnetic incremental permeability, magnetic Barkhausen noise, magnetic needle probe, etc.) were measured to establish the correlations between the magnetization mechanisms, the mechanical properties, and the grinding burn level. Owing to the experimental conditions and ratios between standard deviation and average values, mechanisms linked to the domain wall motions appear to be the most reliable. Coercivity obtained from the Barkhausen noise, or magnetic incremental permeability measurements, was revealed as the most correlated indicator (especially when the very strongly burned specimens were removed from the tested specimens list). Grinding burns, surface stress, and hardness were found to be weakly correlated. Thus, microstructural properties (dislocations, etc.) are suspected to be preponderant in the correlation with the magnetization mechanisms.

“…Therefore, many techniques, especially nondestructive ones, were investigated and utilized for stress measurement and monitoring in many applications. For ferromagnetic materials, Magnetic Barkhausen noise (MBN) technique has been proved as a feasible nondestructive testing and evaluation (NDT&E) method for RS and AS on-site assessment [3]- [5].…”

In this paper, a rectangular excitation is employed for nondestructive assessment of compressive applied stress (0-150 MPa) on Q235 steel using magnetic Barkhausen noise (MBN) technique. The response durations almost keep constant due to the variation rate of applied voltage is fixed whatever the excitation frequency is. After eliminating the excitation induced pulse signal, the ring count feature is extracted to measure the applied stress. The traditional features, root mean square (RMS) and skewness, with sine and triangle excitation are compared with the proposed feature. Ring count presents monotonous relations to the applied stress, and is almost impervious to the excitation frequency, especially when the applied stress more than 75 MPa. Although the sensitivity of ring count feature is less than skewness in low-stress loading situation, it provides high sensitivity as well as RMS feature and better frequency stability, which contributes to the actual applications for stress measurement and evaluation based on MBN technique.
