For nanocrystalline alloy Fe73.5Cu1Nb3Si13.5B9 thermomechanical treatment was carried
out simultaneously with nanocrystallizing annealing (1) or after it (2). It was shown that a
change in magnetic properties for the case 1 is essentially greater than for the case 2.
Complex effect of thermomagnetic and thermomechanical treatments on magnetic properties
was studied in the above-mentioned nanocrystalline alloy as well as in the amorphous
alloy Fe5Co70.6Si15B9.4., During the annealings both field and stress were aligned with the
long side of the specimens. It was shown that the magnetic field, AC or DC, decreases an
effect of loading. Moreover, the magnetic field, AC or DC, applied after stress-annealing
can destroy the magnetic anisotropy already induced under load.
