Abstract

We have studied partitioning of Si in nanocrystalline Fe-Zr-Si-B soft magnetic alloy by atom probe field ion microscopy (APFIM). Unlike our expectation from our previous results in nanocrystalline Fe-Si-B-Nb-Cu alloy, we have found that Si atoms are rejected from α-Fe primary crystals and partitioned into the residual amorphous phase. This result suggests that Si addition does not cause reduction in inherent magnetostriction of α-Fe nanoparticles, but it brings the volume fraction of the α-Fe particles to an optimum value so that the average magnetostriction becomes zero. This conclusion has been strengthened by comparing the changes in magnetostriction constants as a function of Si content in Fe-Zr-Si-B and Fe-Si-B-Nb-Cu alloys.
