“…The occurrence of such precipitation is confirmed by the highresolution TEM image shown in figure 8. This result is also supported by recent electrical resistivity studies of Fe 86 Zr 7 B 6 Cu 1 [5] and Fe 85 Zr 7 B 6 Cu 2 [6] amorphous alloys, for which a change in slope of the electrical resistivity curve was seen at temperatures below the first crystallization temperature. Thus, the small addition of Cu to Fe-Zr-B type alloys accelerates the precipitation of α-Fe nanograins from the amorphous phase.…”

Thermo-magnetic studies combined with transmission electron microscopy of and amorphous and nanocrystalline alloys revealed the precipitation of a single BCC -Fe nanocrystalline phase during the first stage of crystallization and the formation of intermetallic phases, the growth of -Fe nanograins and further precipitation of -Fe nanograins from the residual amorphous phase during the second stage of crystallization. The presence of 1 at% Cu in the second alloy accelerates the precipitation of the single nanocrystalline phase during the first stage of crystallization and facilitates further precipitation of -Fe nanograins from the residual amorphous phase during the second stage of crystallization.

“…During the long lasting debate on origin of such a behavior, found also e.g. in Nanoperm alloys [10,11], various pictures were proposed, including early crystallization, surface crystallization and relaxation phenomena. Due to lacking precise structural data it is hard to distinguish even a main mechanism.…”
