Abstract

Abstract: A 6.5%Si ultra-thin strip with thickness of 0.03 mm was fabricated by using of melt-spinning method, and subsequently annealed at 880 ℃ and 920 ℃ in vacuum furnace, respectively. The evolution of macro and micro texture under different annealing temperatures was investigated by means of X-ray diffraction and EBSD test. The results show that the 6.5%Si ultra-thin strip can be characterized by {001}<100> Cube, {110}<001> Goss and {112}<111> texture. The λ-fiber remains the dominant and the grain size increases gradually with the increase of annealing temperature. Especially, when annealed at 920 ℃, the size dominance of {001}<120> and {001}<100> grains increases gradually, and the unfavorable texture {111}<110> and {111}<112> decrease. Meanwhile, preeminent magnetic inductions of 1.644 T(B₅₀) and iron losses of 5.896 W/kg(P_10/400) are achieved.
