“…Recently, high magnetic field (HMF) has been successfully applied to material design and productions [8][9][10][11][12]. The HMF not only significantly influences the liquid/solid solidification micro-/macro-structures for both ferromagnetic and non-ferromagnetic metals [13], but also a powerful tool to affect the crystallization process of amorphous alloy, texture formation of the crystallized phases [14][15][16][17]. The constant and strong magnetic field shows both magnetic forces and transmits highintensity energy to the atomic scale of matter without contact, thus changing the whole energy of the material phases and dynamic behavior of atomic arrangement, matching and migration [9,11,12,18,19].…”

This work aims to investigate the effects of high magnetic field annealing (HMFA) on the precipitation of α-Fe from Fe 84−x Si 4 B 12+x (x = 1, 3) amorphous precursors. Isothermal annealing process for Fe 81 Si 4 B 15 and Fe 83 Si 4 B 13 amorphous ribbons has been performed with and without the magnetic field. The magnetic field shows the effects of increasing the nucleation rate and decreasing the grain size of α-Fe crystals simultaneously, during the crystallization processes of the investigated amorphous alloys. By applying HMF, α-Fe crystals with more homogeneous distribution and smaller grain size are achieved in the amorphous matrix, which is crucial helpful to improve the magnetic properties for Fe-Si-B amorphous alloys. The mechanism of HMFA affecting the crystallization microstructure is also discussed in the present work.

“…Very recently, high magnetic field (HMF) up to above 10T has been successfully applied to materials design and productions 13,14 . The finding has demonstrated that the magnetic field is a powerful tool to affect the crystallization process of metallic glass and texture formation of the crystallized phases [15][16][17][18][19][20] . In this work, a HMF up to 12T is introduced to the low temperature structural relaxation process of high-boron Fe 71 (Nb 0.8 Zr 0.2 ) 6 B 23 BMG.…”

“…11) Zhuang et al advocated that a high magnetic field has a strong influence on the nucleation process owing to the difference in permeability between the crystal and amorphous phases of the Zr-based bulk metallic glass. 12) In these reports, the samples were annealed in magnetic fields, and then cooled to room temperature. After the thermal treatment, the samples were studied by X-ray diffraction and transmission electron microscopy imaging.…”

Magnetic Field Effects on Crystallization of Iron-Based Amorphous Alloys

et al. 2013

The crystallization behavior of iron-based amorphous alloys has been investigated in high magnetic fields by differential thermal analysis (DTA) and magnetization measurements. DTA of FeSiB amorphous alloys showed that the exothermic peaks shift toward higher temperature under high magnetic fields. At 10 T, peak temperatures of the crystallizations increased approximately 3 K, compared with those at a zero magnetic field. Such a variation in the crystallization peak was not observed in the FeBNbY bulk metallic glass (BMG). In the temperature dependence of the saturation magnetization for the FeSiB amorphous alloy, the sudden increase of the magnetization was found at the crystallization temperatures. The magnetization of FeSiB increased 56 and 40 Am 2 kg ¹1 at the first and second crystallization temperatures, respectively. This magnetization behavior indicates the magnetic transition from the paramagnetic to the ferromagnetic state, accompanying the crystallization, whereas there is only a slight increase in magnetization at the crystallization temperature in FeBNbY BMG. The effect of magnetic field on the crystallization peak as observed from DTA is related to the increase in the magnetization at the crystallization temperature.
