Torsion and stress in amorphous positive magnetostrictive wires

In this paper we report some results on the dependence of the pulsed voltage output on the applied torsion or tensile stress in Fe/sub 77.5/Si/sub 7.5/B/sub 15/ amorphous wires used as magnetostrictive delay lines. The obtained results show a non monotonic dependence of the response of the delay lin...

Summary:In this paper we report some results on the dependence of the pulsed voltage output on the applied torsion or tensile stress in Fe/sub 77.5/Si/sub 7.5/B/sub 15/ amorphous wires used as magnetostrictive delay lines. The obtained results show a non monotonic dependence of the response of the delay line on applied torsion. For applied tensile stress the response could be fitted by a linear curve for as-cast wires and by an exponential curve for annealed wires. The good ratio between minimum and maximum magnetostrictive delay line signals and the absence of hysteresis suggest the possibility to use this technique in load cells and torque sensors.
