“…Recently, Wang et al reported novel alloy design concepts based on the high-entropy, cluster stabilization, and magnetic-intercoupling enhancement mechanisms [194,198,199] [shown in figures 10(b) and (c)]. By using these new approaches, Fe 82.7-85.7 Si 2-4.9 B 9.2-11.2 P 1.5-2.7 C 0.8 MGs with a distinctly high Fe content of 93.5-95.5 wt.% were readily developed [198] (see figure 10(d)).…”

Metallic glasses or amorphous alloys are an important engineering material that has a history of research of about 80-90 years. While different fast cooling methods were developed for multi-component metallic glasses between 1960s and 1980s, 1990s witnessed a surge of research interest in the development of bulk metallic glasses. Since then, one central theme of research in the metallic-glass community has been compositional design that aims to search for metallic glasses with a better glass forming ability, a larger size and/or more interesting properties, which can hence meet the demands from more important applications. In this review article, we focus on the recent development of chemically complex metallic glasses, such as high entropy metallic glasses, with new tools that were not available or mature yet until recently, such as the state-of-the-art additive manufacturing technologies, high throughput materials design techniques and the methods for big data analyses (e.g. machine learning and artificial intelligence). We also discuss the recent use of metallic glasses in a variety of novel and important applications, from personal healthcare, electric energy transfer to nuclear energy that plays a pivotal role in the battle against global warming.

“…The dual-phase nanostructure is usually obtained by annealing amorphous precursors. Promotion of the α-Fe nanograins precipitation but suppression of their over growth is crucial to achieve high Bs and avoid increases in coercivity (Hc) and W [10] . The nanostructure formation mechanism has been studied in numerous work.…”

“…Due to their potential in energy saving, Fe-based amorphous/nano-crystalline alloys have increasingly received the attention of researchers in recent years. [1][2][3][4][5] Ever since the successfully development of the FINEMET® alloy with the typical composition of Fe 73.5 Si 13.5 B 9 Nb 3 Cu 1 , [6][7][8][9][10][11][12][13] it has been well recognized that the addition of heavy transition metals such as Nb not only helps increase the ability to form amorphous state in the initial solidification process, but also plays a crucial role in the nano-crystallization process such as annealing the amorphous alloy. It has been reported that the Nb atoms could suppress α-Fe grain growth by inhibiting atomic diffusion, which is due reasonably to the large atomic size of Nb.…”

The addition of early transition metals (ETMs) into Fe-based amorphous alloys is practically found to be effective in reducing the α-Fe grain size in crystallization process. In this paper, by using ab initio molecular dynamics simulations, the mechanism of the effect of two typical ETMs (Nb and W) on nano-crystallization is studied. It is found that the diffusion ability in amorphous alloy is mainly determined by the bonding energy of the atom rather than the size or weight of the atom. The alloying of B dramatically reduces the diffusion ability of the ETM atoms, which prevents the supply of Fe near the grain surface and consequently suppresses the growth of α-Fe grains. Moreover, the difference in grain refining effectiveness between Nb and W could be attributed to the larger bonding energy between Nb and B than that between W and B.
