Abstract:
The deformation of amorphous materials causes a change in their magnetic properties. If it occurs within the elastic region, such changes are reversible and can be used to control stresses. This applies both to the amorphous alloys themselves and to composites with embedded amorphous microwires. The new experimental results on monitoring of the applied tensile stresses in Fe-based amorphous microwires after different regimes of treatment are presented. We investigated the amplitude of the Electro-Motive Force (EMF) signal due to the Barkhausen effect, the saturation magnetostriction and the coercivity. We used a non-contact method for stress monitoring of ferromagnetic microwires. It was found that the dependence of the EMF signal on the axial tensile stress of microwire exhibits a maximum. We observed a significant increase in the maximum of the EMF signal for microwires after annealing and its shift to higher tensile stresses. Using the obtained data, we evaluated the possibility of stress monitoring in a composite material containing such microwires.
