Origin of high glass forming ability of Y-containing FeB-based alloys

Composition formulas of Fe-based transition metals-metalloid bulk metallic glasses derived from dual-cluster model of binary eutectics

“…[B-B 2 Fe 8 ], after being matched with each of the four possibilities, produces the following formulas: [B-B 2 Fe 8 ]Fe = Fe 75 B 25 , [B-B 2 Fe 8 ]BFe 2 = Fe 71.4 B 28.6 , [B-B 2 Fe 8 ]B = Fe 66.7 B 33.3 , and [B-B 2 Fe 8 ]B 2 Fe = Fe 64.3 B 35.7 . Melt-quenched Fe-B metallic glasses are usually formed in the composition range of 72–88 at.% Fe 29 – 32 . The Fe-richest [B-B 2 Fe 8 ]Fe is then chosen because it is the only one falling in the glass forming range.…”

The Influence of Technological Parameters of the Casting Process on the Structure and Selected Properties of Iron-Based Metallic Glasses

“…Multicomponent Fe-based amorphous alloys attract attention due to their good soft magnetic properties combined with high glass-forming ability [1,2]. These features enable to produce soft ferromagnetic materials in different forms of ribbons, rods, rings or plates.…”

Investigation of magnetic properties of Fe61Co8Zr4−xY2+xNi5Nb5B15 amorphous alloys (x=0, 1) in the form of ribbons

“…In the literature on amorphous and nanocrystalline materials [18][19][20][21][22][23], there are many examples of alloys containing Zr and/or Y. Based on these and our own studies, it can be postulated that a higher Zr and/or Y content in the alloy causes a significant deterioration in the so-called soft magnetic properties; this can be observed as: reduction in saturation magnetization and magnetic permeability values and increase of the coercivity and core losses over a single magnetization-demagnetization cycle.…”
