Description
Summary:The effect of annealing temperature on the structure and magnetic properties of nanocrystalline Fe sub 82.5-x Cu sub 1 Nb sub 3 Si sub 13.5 B sub x (x=5-13 at%) ribbons was studied. Magnetic induction decreased considerably with increasing boron content. The highest magnetic permeability at 50 Hz and H=0.4 a/m was achieved upon annealing at 550 deg C of 26 mu m thick ribbons with 9% B. This also occurred for 20 mu m thick ribbons with 9% B was about 530 deg C. The results suggested that it takes an appropriate combination of annealing parameters and ribbon thickness to achieve optimum magnetic properties. The nanocrystallization process can be stimulated effectively by changing the boron content. As-cast ribbons with 7% boron exhibited the highest ductility.
