摘要: This paper presents the results of investigation on influence temperature magnetoelastic characteristics two ring-shaped cores, made Fe70Ni8Si10B12 amorphous alloy. The cores were annealed for 1 h at 350 and 400°C, respectively. compressive force F was applied perpendicular to direction magnetizing field H in sample. Special cylindrical backing enables application uniform stress σ wound ring A resistive furnace heated experimental set-up. Results presented indicate a significant Information about this material may be useful sensor development. Also will create new possibilities development physical model effect.
