Nano-crystallization behavior and magnetic domain evolution in commercial Fe–Si–B metallic glass

A Review of Fe‐Based Amorphous and Nanocrystalline Alloys: Preparations, Applications, and Effects of Alloying Elements

“…These materials are an important part of electronic products and have a great influence on human production and lifestyle. [1,2] Figure 1 shows magnetic properties of typical soft magnetic materials. Silicon steel occupies most of the market of soft magnetic materials, but its effective permeability (μ e ) is too low, which leads to great losses in power generation and transmission.…”

Effect of Heat Treatment Temperature on the Crystallization Behavior and Microstructural Evolution of Amorphous NbCo1.1Sn

“…In this regard, nanocrystallization of amorphous precursors through heat treatment shows particular promise for fabricating high-quality nanostructured materials in a scalable manner. − This method enables the production of a highly homogeneous amorphous alloy without chemical segregation. By modifying the heat treatment conditions or adjusting the supersaturated amorphous composition, it enables to design the final microstructure with greater flexibility. This approach finds widespread application in the nanostructuring of soft magnetic materials, allowing the production of fine grain sizes as small as 10 nm while keeping an amorphous phase remaining at the grain boundaries. − Overall, the use of amorphous precursors for fabricating nanocrystalline structures provides a pathway to obtain materials with the desired properties, improved performance, and expanded application possibilities.…”

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]. In particular, Fe-based metallic glasses are especially interesting as they present unique characteristics in comparison with conventional Fe-based crystalline alloys [6,8].…”
