Abstract:
The rapidly quenched Fe73.5Cu1Mo1.5V1.5Si13.5B9 alloy has been melt-spun to form ribbons where the refractory element of Nb has been replaced by equiatomic ratio of Mo and V in order to study the effect of these refractory elements on the magnetic properties. The ribbons have been annealed in a controlled way in the temperature range of 300°C to 600°C for 30 minutes in order to study its effect on structural parameters. DTA curve is characterized by the presence of α-Fe(Si) phase in the range of 458°C zation in the amorphous relaxed state is associated with structural relaxation. In the nanocrystalline state magnetization decreases because relative amount of Fe in the α-Fe(Si) nanograins decreases and relative amount of non-magnetic Mo, V and B in the amorphous matrix increases.
