Abstracts

EN

The following paper presents the results of the investigation on the influence of the torque on the magnetic characteristics of the Hitperm-type Fe_{41.5}Co_{41.5}Cu_1Nb_3B_{13} alloy, in as-quenched and nanocrystalline state. The methodology of application of the torque to the ring-shaped core is also described. This methodology gives a possibility of achieving uniform shearing stresses in the core. The results indicate that shearing stress sensitivity of Hitperm-type alloys depends on the annealing and nanocrystallization process. This effect should be considered during the development of magnetoelastic torque sensors.
