Effect of P on glass forming ability, magnetic properties and oxidation behavior of FeSiBP amorphous alloys

Amorphous gray iron for concrete reinforcement

“…Consequently, the value of the Tx parameter increases, indicating an increase in GFA. This can be explained by the fact that P has a much smaller atomic radius than that of Fe and Cr, and therefore, by increasing the content of P an increasing of the atomic packing density of the liquid structure is favored [6]. The higher the atomic packing density, the easier it is to obtain the amorphous structure.…”

“…Incorporation of phosphorous (P) into Fe-Cr-Si alloys effectively enhanced the glass-forming ability (GFA) [5,6], but at the same time increasing P content lead to an increase in hardness and tensile strength and decrease in ductility. The costs of producing amorphous metallic materials only from pure elements are significantly higher than the production in combination with ferrous alloys.…”

Development of high Bs Fe–Ni-based metal amorphous nanocomposite by optimization of glass-forming ability

“…It was recognized that significant improvements in Bs can be achieved by increasing the magnetic element content, which led to the development of NANOPERM by Suzuki et al [30]. Since then, several studies have found significant improvements in Bs in Fe-based amorphous/nanocrystalline alloys by increasing magnetic element content [73][74][75][76][77][78]. However, this comes at the expense of glass forming elements, which can reduce GFA.…”

Polymorphic Transformation and Magnetic Properties of Rapidly Solidified Fe26.7Co26.7Ni26.7Si8.9B11.0 High-Entropy Alloys

“…Until now, more than three hundred reported HEAs have been designed based on more than thirty elements [5]. In order to increase the specific strength and further explore the soft magnetic properties of HEAs, elements like B, Si, P, and/or C with relatively small atomic weights are introduced into FeCoNi medium entropy alloys [28,29,30,31]. Surprisingly, some of these types of HEAs are able to easily form metallic glasses [28,29,30,31].…”

Surprisingly, some of these types of HEAs are able to easily form metallic glasses [28,29,30,31]. Then the high-entropy glass-forming composites could be an excellent candidate to fabricate metallic glass composites since the dominant crystallization products are single FCC solid solution for some cases [32,33].…”
