“…It should also be noted that the diffraction peaks corresponding to Fe 23 C 6 phase disappear in the XRD pattern of A-T p2 , suggesting that the Fe 23 C 6 phase precipitated in the first crystallization event may have been fully or partially dissolved before the second crystallization event for A. The Fe 23 C 6 phase is metastable quasicrystal-like phase and unstable at an elevated temperature, [17,18] which may account for the disappearance of Fe 23 C 6 phase in A-T p2 . Some studies [18][19][20] have shown that unique network like structure such as Fe 23 (B,C) 6 phase can lead to the high stability of the supercooled liquid against crystallization.…”

Moreover, the mother alloy of B fabricated using industry raw material still contains some harmful impurities after fluxing treatment, which serves to suppress the formation of Fe 23 (B,C) 6 phase due to the competition of crystalline phase.…”

Pseudo-ternary Fe 78 P 13 C 9 (the real composition is Fe 77.6 Si 1.4 P 12.7 C 8.3 ) bulk metallic glasses (BMGs) with the maximum diameter of 1.5 mm based on industrial raw materials has been prepared by J-quenching technique using the master alloys with fluxing treatment, whereas fully amorphous alloy rod with the diameter of 1.0 mm cannot be obtained by the same preparation method using the master alloy without fluxing treatment. It is indicated that the glass formation ability (GFA) of the present Fe-based alloys based on industrial raw materials can be greatly enhanced through fluxing treatment. For comparison, the amorphous alloy rod with the same composition based on the pure raw materials has also been prepared by the same preparation technique and the critical diameter for fully glass formation gets to 2.0 mm. The DSC result indicates that the present Fe-based BMG based on industrial raw materials reveals higher thermal stability compared with the BMG based on pure raw materials. The magnetic tests show that the saturation magnetizations of the present Fe-based BMGs prepared by pure raw materials and industrial raw material are around 1.40 T, and have no significant difference. Compressive tests show that the present Fe-based BMG based on industrial raw materials exhibits higher compressive fracture strength (3.11 GPa) and slightly less plastic strain (0.8 pct) compared with the BMG based on pure raw materials with the same composition.

“…Moreover, due to the lower glass forming ability, the largest diameter of the FePCbased BMGs prepared by copper mold casting is 2.5 mm. [15] However, with the aim of exploring Fe-based glassy alloys with high GFA and high Is, the effects of Si and Mo additions in FePCB alloy have been studied in [23] for the extension of practical applications in power transformers.…”

The discovery and large scale investigation of rapidly solidified alloys have brought to light, in the last three decades a new scenario in basic and applied magnetism. With a range of composition and microstructural states unavailable to conventional materials, the rapidly quenched alloys have in fact demonstrated unprecented versatile properties, provide unique opportunities in applications and enlarged the domain of physical theories. In this paper, the basic magnetic features of two classes of magnetic bulk metallic glasses, soft and hard magnetic alloys, will be briefly highlighted

“…So far, the investigated minor additions for Fe-based BMGs have included: (1) variations of the metalloid content (B [17], C [18], Si [19], P [20]), (2) rare earth additions such as Sm [21], Y [22,23], Er [24], Dy [25], Tb [26], and (3) transition metal additions such as Mo [27,28], Ni [29], Nb [30,31], Ta [31], Co [32], Cu [33]. In particular, addition of transition metals has been useful to develop new Fe-based BMGs with high GFA at low cost.…”

Abstract:A new Fe-based bulk metallic glass with superior glass forming ability, Fe 46 Cr 15 Mo 14 C 15 B 6 Nb 4 , was developed based on the Fe-Cr-Mo-C-B alloy system by minor addition of niobium. The effects of niobium addition on glass formation of the Fe 50-x Cr 15 Mo 14 C 15 B 6 Nb x (x=0, 2, 4 and 6 at.%) alloys were investigated. The optimum addition content of niobium was determined as 4 at.% by X-ray diffraction and differential scanning calorimeter analysis. A fully amorphous rod sample with 3 mm in diameter was produced by using commercial-grade raw materials and a copper mold casting technique. This alloy shows an ultimate compressive strength of 1920 MPa and Vickers hardness 1360 HV, which is two to three times that of conventional high strength steel and suggests a promising potential for applications combining outstanding corrosion and wear resistance properties. The crystallization kinetics studies found that the activation energies for glass transition, onset of crystallization and crystallization peak were higher than those of other reported Fe-based bulk metallic glasses. The value of the fragility parameter m for the Fe 46 Cr 15 Mo 14 C 15 B 6 Nb 4 alloy was calculated to be 34, indicating that the Fe-Cr-Mo-C-B-Nb alloy system is a strong glass former according to the Angell's classification scheme. It is inferred that 2 the more sequential change in the atomic size, the generation of new atomic pairs with large negative heats of mixing and the amount of oxygen in the molten liquid neutralized into niobium oxides provide a synergetic effect for the remarkably improved glass-forming ability and thermal stability.
