摘要：

The microstructure and soft magnetic properties of crystallization-induced alloys in Fe-Zr and Fe-Zr-B systems were investigated. Melt-spun amorphous Fe92Zr, and Fe91Zr7B, alloys were found to crystallize through two distinct stages; the first and second stage are due to primary crystallization of a nanocrystalline b.c.c. phase and crystallization of a residual solute-enriched amorphous phase into Fe3Zr and Fe2Zr respectively. The addition of B into amorphous Fe-Zr alloys causes the refinement of the primary b.c.c. crystals, resulting in a significant improvement of the soft magnetic properties of the annealing-induced alloys. Grain coarsening of the nanocrystalline b.c.c. phase as well as the formation of compounds is suppressed by the addition of B. This is presumably because of a significant increase in the crystallization temperature of the residual amorphous phase resulting from the combined redistribution of Zr and B elements between the primary and parent amorphous phases.
