Popis: | We stated that crystalline grains in the nanocrystalline alloys obtained by a proper annealing consist of the ordered α-FeCo phase. However, in the partially crystallized alloys during a rapid solidification α-FeCo phase is completely disordered. In both, the amorphous and nanocrystalline samples broad disaccommodation spectra are observed. The activation energies of relaxation processes range from 1.00 to 1.34 eV and from 1.47 to 1.82 eV for the amorphous and nanocrystalline samples, respectively. |
