摘要
Primary precipitation phases in amorphous Fe-Si-B-Nb alloys with compositions around FINEMET and bulk amorphous alloys have been investigated. On the base of new and previous TEM and XRD results concentration areas and condition for formation of the metastable phases have been determined. Role of the primary metastable phases with compositions close to the mean composition of the alloys in the processes of nanostructuring is discussed, in particular the role of hexagonal phase with the distorted alpha-Mn type structure is emphasized.
