Summary:Variations in the electronic properties of amorphous Fe-Cu-Nb-Si-B alloys during crystallization have been studied by methods of positron annihilation spectroscopy. The measurements of the positron lifetime in samples and the angular distribution of annihilation photons have demonstrated substantial variations during crystallization. There is a correlation of the results with the performed measurements of the thermopower. The experimental results allow the assumption that degenerate electron gas is not formed in the amorphous alloys under study, and localized electrons participate mainly in the conduction. It can be suggested that the main role in formation of the amorphous alloy structure is played by the covalent bond. The spectrum of momentum distribution of the amorphous alloy differs little from the pure iron spectrum. Irradiation induces vacancy-copper complexes in the amorphous alloy.
