“…Further increase in the AC field does not significantly increase the output voltage response. Notably, this can be attributed to the nonlinear magnetostrictive behavior of nickel, wherein the rate of switching of domains decreases with an increase in the applied field [50], thereby decreasing the piezomagnetic coefficient and corresponding decrease in the ME response. Similar behavior of dependence of ME coefficient on applied ac magnetic field was also reported earlier by Aubert et al [51,52].…”

Owing to the multifunctional behavior possessed by magnetoelectric (ME) composites, they are a sought after materials for various magnetic ﬁeld sensing applications. This article proposes a three-directional magnetoelectric based embedded magnetic sensor which has been fabricated using the press-ﬁt technique. The employed fabrication method negates the use of epoxy in the ME sensor thus enabling its use at elevated temperatures in excess of 100ﬃC. To establish the relative efﬁcacy of embedded sensor over the conventional layered structure, a layered sensor has also been fabricated and tested. The fabricated sensors are tested using an experimental setup capable of producing ac and dc bias magnetic ﬁelds in three coordinate directions. Experiments are performed for various dc magnetic ﬁeld conditions including x, y, z directions and their simultaneous combinations. Under all testing conditions, the embedded sensor shows a signiﬁcantly high response as compared to its layered counterpart. Moreover, a 67 % increase in sensing distance is observed in case of embedded sensor over the layered structure. Additionally, the effect of magnetic ﬁeld generated by double magnet system and single magnet system on the sensor performance has also been demonstrated, wherein the embedded sensor is observed to be marginally affected whereas the layered sensor is adversely affected. Finally, similar measurements are performed at elevated temperatures up to 100ﬃC and it is observed that the novel embedded sensor has reliable sensing capabilities in aggravated thermal environments even in excess of 100ﬃC, whereas, the layered sensor loses its sensing capabilities above 50ﬃC. Thus, the proposed 3-directional embedded magnetic sensor offers a better response under all conditions of magnetic ﬁeld and temperature over the layered counterpart and can thus be a reliable alternative for the latter.

“…The most advanced magneto-elastic coupling models (i.e. taking into account the multiaxial stress state or the Villari reversal) derive their precision from an accurate description of the microstructure including appropriate scale transitions [14]. However, these models are too slow and lead to more qualitative than quantitative estimations to allow for an efficient identification process.…”

It is devoted to the experimental study of the creep of an aluminum alloy containing microscopic inclusions. It was found that preliminary electric ignition (j<3· 106 A/m2) of the material leads to an increase in the creep of the samples. The reasons for the observed changes are associated by the authors with the formation of local areas of high mechanical stresses near the interface of the inclusion - matrix interface. The assessment of the level of emerging local thermoelastic stresses in aluminum deltaT ~ 35 MPa, as well as the characteristic size of such areas (~ 2 µm). The observed increase in creep is determined by the resultant effect of residual stresses and stresses of thermal nature, which contributes to the creation of additional local sources of deformation in the interfacial regions. Local stress concentrators lead to a local increase in the number of mobile dislocations, which is the main reason for the change in the mechanical properties of the aluminum alloy under consideration with microscopic inclusions.
