“…Subsequently the as-prepared alloy ingots were fluxed in B 2 O 3 fluxing agent at an elevated temperature for at least 4 h under a vacuum of $10 Pa. After flux treatment, samples were cooled down to room temperature and then were subject to J-quenching technique. As a result, Fe 80 P 13 C 7 alloy rods with the diameters ranging from 1.0 mm to 2.0 mm and the length of a few centimeters had been prepared by J-quenching technique [8]. The Fe 80 P 13 C 7 meltspun glassy ribbons were produced by the melt-spinning technique with the fluxed alloy ingots and the thickness of the resultant glassy ribbons is $25 lm.…”

“…The amorphous nature of both bulk rods and melt-spun glassy ribbons had been confirmed by X-ray diffractometer (XRD) and transmission electron microscopy (TEM). The details can be found elsewhere [8]. In addition, the diameter of all BMG samples used in the present study is 1.5 mm to avoid the influence of sample size.…”

“…The crystallization behavior of melt-spun glassy ribbons of this alloy had been extensively studied in the subsequent several decades [6,7]. Most recently Fe 80 P 13 C 7 BMG with a maximum diameter of 2.0 mm has been synthesized by means of the combination method of fluxing treatment and J-quenching technique [8]. So it provides an opportunity to perform the comparative study on the crystallization behavior between Fe 80 P 13 C 7 BMG and the melt-spun glassy ribbon.…”

“…Many studies have shown that fluxing technique is an effective method in removing heterophase impurities from a molten specimen and enhancing GFA of alloys. There is a high level of impurities in industrial raw materials, and thus it can be expected that the GFA of alloys based on industrial raw materials can be greatly improved by means of fluxing treatment.…”

Bulk quasi-ternary Fe 80 P 13 C 7 (the real composition is Fe 79.4 Si 1.0 P 12.8 C 6.8 ) glassy rod alloy with the maximum diameter of 1.0 mm was prepared by combining fluxing treatment and J-quenching technique using industrial cast iron and Fe-P alloys as raw materials. The result shows that the present Fe-based bulk metallic glass (BMG) exhibits good soft magnetic and mechanical properties with a high saturation magnetization of 1.43 T, a low coercivity of 7.2 A m À 1 (for as-cast melt-spun glassy ribbon) and a high fracture strength over 2.75 GPa. The effects of fluxing treatment on the glass-forming ability (GFA), thermal stability, and magnetic properties of the present Fe-based amorphous alloy fabricated using industrial raw materials have also been investigated. It is indicated that the GFA of the present Fe-based alloy prepared using industrial raw materials is greatly improved through fluxing treatment, which should be attributed to the effective elimination of the impurities in alloy. In addition, soft magnetic properties of the present Fe-based amorphous alloy can be significantly improved by fluxing treatment, and the melt-spun glassy ribbon obtained from the fluxed mother alloy has a lower coercivity and higher Curie temperature compared with the melt-spun glassy ribbon obtained from un-fluxed mother alloy. The improvement in soft magnetic properties should be attributed to the purification of the master alloy through fluxing treatment, which results in more uniform atomic arrangement structure in the produced amorphous alloy.
