| This paper presents the experimental results of the magnetic and magnetoelastic investigation on the properties of Fe70Ni8Si10B12 amorphous alloy, subjected to thermo-magnetic treatment. Samples were annealed at temperature 350^circC for 1 hour, in parallel magnetic field (4 kA/m), as well as in transverse field (350 kA/m). Sample annealed without magnetic field was also tested. Magnetoelastic tests were performed under uniform compressive stress, applied to the ring-shaped core, perpendicularly to the direction of magnetizing field. The results indicated that the thermo- -magnetic heat treatment changes the magnetic characteristics, but does not have a significant influence on the coarse of magnetoelastic characteristics of Fe70Ni8Si10B12 amorphous alloy. |
