Effect of the partial substitution of V for Nb on the magnetic properties of Fe-based nanocrystalline alloy

Abstract

Abstract: The variation of the magnetic properties of the nanocrystalline alloys for the partial substitution of V for Nb with crystallizing treatment temperature and time was investigated. The variation law of the magnetic properties with the annealing temperature and time is essentially the same. The magnetic properties of the Fe-based nanocrystalline alloys for the partial substitution of V for Nb reduce, and the crystallizing treatment temperature of the alloys increases. The optimum properties of Fe74Cu1Nb3Si13B9 nanocrystalline alloys crystallized at 550 degreesC x 60 min are mu (0) = 9.2x10(4), mu (m)=54.8x10(4), H-c=1.14 A/m and B-s=1.26 T. The best properties for Fe74Cu1Nb2.5V0.5Si13B9 alloys annealed at 560 degreesC x 60 min are mu (0)=8.79x10(4), mu (m)=50.18x10(4), H-c=1.26 A/m and B-s=1.24 T.
