Induced magnetic anisotropy and the structure of nanocrystalline Fe-Co-Cu-Nb-Si-B alloys with different content of Co: II structure of alloys with an induced magnetic anisotropy
Tóm tắt
A connection has been established between the structural state (phase composition) of the nanocrystalline alloys Fe73.5 − x

Cu1Nb3Si13.5B9 (x = 0, 10, 20, 30) and the type of the induced magnetic anisotropy (IMA), which is formed in the process of thermomechanical treatment (TMechT), on the one hand, and its thermal stability, on the other hand. It is shown that the addition of cobalt entails a decrease in the quantity of Fe-Si grains and the formation of phases that contain Fe-Co-B. The induced magnetic anisotropy depends on the volume fractions of structural components, their elastic properties, and coherent bonding of their crystal lattices.
