摘要：

The alloy (Fe0.7Co0.3)(88)Hf4Mo2Zr1B4Cu1 is studied to obtain materials with improved thermal stability. The effect of the nanocrystallization conditions that occur during heat treatment (HT) and thermomechanical treatment (TMechT) in air at temperatures of 520-620A degrees C on the structure of the alloy, as well as its magnetic properties and their thermal stability, is considered. Longitudinal magnetic anisotropy is shown to be induced in the alloy in the course of TMechT; the easy magnetization axis of the anisotropy is parallel to the long side of the ribbon. The alloy specimens subjected to heat and thermomechanical treatment have different magnetic characteristics. The (Fe0.7Co0.3)(88)Hf4Mo2Zr1B4Cu1 alloy is found to surpass the (Fe0.6Co0.4)(86)Hf7B6Cu1 and (Fe0.7Co0.3)(88)Hf7B4Cu1 alloys studied in [1] in the thermal stability of the magnetic properties. The magnetic properties of the alloy after nanocrystallization, which occurs in the course of TMechT (sigma = 250 MPa) at 620A degrees C for 20 min, hardly change during annealing at 550A degrees C for 26 h.
