The initial permeability, density and microstructure are compared as a function of the annealing temperature for nanocrystalline Fe86Zr7B6Cu1 and Fe73.5Si13.5B9Nb3Cu1 alloys. In the optimum annealed state where the initial permeability is the maximum, flat disc-shaped bcc-Fe(Zr) grains were observed by transmission electron microscopy in Fe86Zr7B6Cu1 in contrast to equiaxed bcc-Fe(Si) grains in Fe73.5Si13.5B9Nb3Cu1. X-ray diffraction revealed a preferred orientation of the bcc grains and large internal stresses in the nanocrystalline Fe86Zr7B6Cu1 alloy. All these observations may partly contribute to the fact that in the optimum annealed state, the initial permeability is much higher for Fe73.5Si13.5B9Nb3Cu1 than for Fe86Zr7B6Cu1.
