摘要The research object in that work is magnetically soft amorphous Fe-Si-Nb-Cu-Mo-B alloy. That and same alloy systems was named as Finemet material. The sample is an amorphous ribbon, which has thickness of 20…30 μm, it was producing by melt spinning method.
The samples were studied using methods of calorimetry, dilatometry and non-ambient x-ray diffraction analysis. The alloy was heat treated. Data about thermal effects, changes in geometric dimensions, changes in the phase composition, and about critical points are obtained. Interval of nanocrystallic state existence for heating rate 0.3…0.5 o/sec was determined.
