摘要：

Nanocrystalline alloys (Fe0.6Co0.4)(86)Hf7B6Cu1 and (Fe0.7Co0.3)(88)Hf7B4Cu1 have been investigated to obtain materials with improved thermal stability and new features. In order to make the alloys produced by melt quenching on a rotating wheel nanocrystalline, they have been subjected to heat (HT) and thermomechanical (TMechT) treatments. The effect of HT and TMechT conditions on the magnetic properties, thermal stability, and structure of the alloys has been studied. The optimal HT conditions for obtaining the minimum values of the coercive force (H (c)) in the alloys have been determined. It is shown that TMechT of the alloys leads to the induced longitudinal magnetic anisotropy with the axis of easy magnetization along the long side of the ribbon in the studied temperature range of 520-620A degrees C. It has been established that the alloys (Fe0.6Co0.4)(86)Hf7B6Cu1 and (Fe0.7Co0.3)(88)Hf7B4Cu1 are thermally unstable at temperatures above 500A degrees C.
