Kinetics and mechanism of structural transformations of Fe75Ni2Si8B13C2 amorphous alloy induced by thermal treatment

► Investigates multi-step structural transformation of iron-based amorphous alloy. ► Kinetic parameters corresponding to each of the steps were evaluated. ► Kinetic triplets for the first two steps of the crystallization were established. ► Divergence between experimental and theoretical curves is the result of secondary nucleation processes. ► Complexity of third step of crystallization makes it impossible to determine its kinetic triplet.
