Effects of Ni and Co alloying on thermal, magnetic and structural properties of Fe-(Ni,Co)-P-C metallic glass ribbons

Role of compositional changes on thermal, magnetic, and mechanical properties of Fe-P-C-based amorphous alloys

“…[36,37] It is also suggested that the Ni constitute creates atomic pairs with smaller negative heat of mixing leading to the weakening of average bonding strength and the reduction of characteristic temperatures. [21,26,38] Moreover, the DSC curve of Fe 75 Ni 5 P 13 C 7 alloy shows that the crystallization region and the melting transition stage happen in a narrower range of temperature without forming two-step events, compared with sample S1. This result reveals that the Ni-added alloy has a chemical composition near the eutectic composition.…”

“…The thermal behavior of sample S3 can be also described by this fact that Co addition leads to the creation of chemical short range orders in the form of Fe 3 Co type clusters inducing the variety of crystallization events during the heating process. [26] When the Ni and Co elements are simultaneously increased into the system (S4), the thermal peaks of amorphous ribbon become similar to the Fe 80 P 13 C 7 composition, so that the crystallization event includes two distinguished peaks. Moreover, T g , T x , and T l values are substantially declined and the GFA indicators, i.e., T rg and ∆T x , are improved in the sample S4.…”

“…Moreover, tuning the comprehensive properties of Fe-P-C alloy is still one of the most heated debates. [26][27][28][29][30] Therefore, we made an effort to design and fabricate alloying compositions based on Fe-P-C system and optimize the mentioned properties to achieve an Fe-based amorphous alloy for the promising applications. To reach this goal, several elemental constitutes with different atomic features were picked out to add into the Fe-P-C system, somehow to improve the comprehensive properties.…”

Evaluation of the Effect of Minor Additions in the Crystallization Path of [(Fe0.5Co0.5)0.75B0.2Si0.05]100-xMx Metallic Glasses by Means of Mössbauer Spectroscopy

“…Nowadays, metallic glasses (MGs) are a well-established type of material, characterized by their lack of long-range order structure, that can be produced in several physical forms (powders [1], ribbons [2], coatings [3], microwires [4,5], bulks [6], magnetorheological fluids [7], etc.) and have a potential variety of applications in several fields: (a) magnetism, including sensors or choke coils [8,9]; (b) electrocatalysis, for example, in fuel cells [10]; (c) biomedicine with stents or orthopedic surgeries [11][12][13][14], (d) engineering, for example with the development of micro electro-mechanical (MEMs) devices [15] and in environmental applications like the catalytic degradation of toxic organic molecules [16] or radiation shielding properties of newly developed FeBCSiP alloys [17].…”

Densification and heterogeneity enhancement of a Fe-based metallic glass under local plastic flow

“…著提高，硬度分布变得更广泛 [22] 玻璃弛豫所观察到的 Tc 向高温方向移动截然不同 [25,26] 。然而，如图 3(b)所示，总 的释放焓(H)随着压力的增加呈现出轻微的下降趋势，相对于 FSB-0 样品的 H 值(-110.8 J/g) ，变形后样品的H 依次降低，从 FSB-5 样品的-107.5 J/g，分 别降为 FSB-15 的-101.6 J/g、FSB-25 的-99.4 J/g 和 FSB-35 的-97.9 J/g。在金属玻 璃中，较低的能量通常对应于原子较密排的状态 [27]…”
