Abstract

This paper presents experimental results of the magnetic and magnetoelastic investigation on the properties of Fe25Ni55Si10B10 amorphous alloy subjected to thermal treatment. During the magnetoelastic tests the uniform compressive stress was applied to the ring-shaped core perpendicularly to magnetizing field direction. Significant changes of magnetoelastic characteristics due to thermal treatment as well as Villari point for the core annealed at 350 úC were observed.
