Evolution of a sharp {110} texture in microcrystalline Fe₇₈Si₉B₁₃ during magnetic crystallization from the amorphous phase

Abstract

The effect of magnetic crystallization on texture evolution and control in nanocrystalline materials has been studied using a melt-spun amorphous Fe₇₈Si₉B₁₃ alloy. The magnetic crystallization was conducted at temperatures ranging from 653 to 853 K in a magnetic field up to 6 T. The temperatures used for magnetic crystallization were chosen on the basis of the Curie and crystallization temperatures of the amorphous phase, and the Curie temperature of the crystallized phase. The resultant microstructure was characterized by X-ray diffraction and FE-SEM/EBSP/OIM techniques. It was found that a sharp {110} texture developed when the amorphous precursor was crystallized at 853 K in a magnetic field of 6 T applied in a direction parallel to the ribbon surface.
