Abstract

Crystallization of Fe₈₂Si₂B₁₆ and Fe₈₂Si₄B₁₄ metallic glasses upon heat treatment has been studied. The amorphous ribbons have been isothermally annealed at different temperatures (673, 693, 733 and 743 K) and for various times (from 15 min to 78 hours). Phase compositions and the sequence of their appearance in dependence on the annealing temperature and time have been established.
