- Abstract:
- Paper presents results of the investigation on the magnetoelastic properties of Fe73.5Nb3Cu1Si13.5B9 alloy in amorphous and nanocrystalline state as stress and force sensor. The new method of applying stress to the ring core of sensor made of soft magnetic material such as nanocrystalline alloys is presented. In this method the distribution of stresses in the ring core is uniform, so even brittle magnetic materials (like nanocrystalline) may be used as stress sensors. The experimental results indicate that stress and force sensor applications require special parameters of the heat treatment of the sensing element. For this reason the optimal treatment parameters for the cores of inductive components should not be applied for cores of the stress sensors.
