Enhancement of glass-forming ability of CoFeBSiNb bulk glassy alloys with excellent soft-magnetic properties and superhigh strength

Preparation of thin ribbon and bulk glassy alloys in CoFeBSiNb(Ga) using planar flow casting and suction casting methods

“…Man, H. Sun et al [4] was selected because it has enhanced glass forming ability (GFA). Co-based master ingots with nominal composition Co 46 Fe 20 B 23 Si 5 Nb 6 have been prepared in a vacuum furnace.…”

“…Since then, Fe and Co-based BGA, which have been produced by casting methods with higher thickness were studied. Co-Fe-B-Si-Nb bulk glassy alloys show high glass-forming ability (GFA), excellent soft magnetic properties, super high strength, making them a promising system for industry applications [4][5][6]. Our effort was to assess the feasibility of preparation of amorphous Co-Fe-B-Si-Nb based alloys in various shapes and with different thickness.…”

“…In fact, soft magnetic materials are one of the most important components for power electronics, electronic compass, electronic current transformers [1][2][3], and so on. Among the magnetic materials, ferromagnetic bulk glassy alloys (BGAs) are an important components due to their excellent magnetic properties, and since the Fe-(Al, Ga)-metalloid system was synthesized for the first time in 1995 [4], a number of Fe-and Co-based BGAs have been developed for the purpose of applications as functional and structural materials [5][6][7][8][9][10][11][12]. Among them, Co-based BGAs are drawing increasing attention due to their excellent softmagnetic properties, such as high saturation magnetization (I s ), low coercive field (H c ) and high effective permeability (l e ) [8,10,13], especially for the amorphous wire and ribbons, which exhibit giant magneto-impedance (GMI) effect, that can be developed as high-sensitivity sensor materials [14][15][16].…”

“…These glasses also display excellent mechanical strength combined with magnetic properties [7][8][9][10][11][12][13][14][15]. Minor addition of alloy components appears then an effective tool to get better GFA [16].…”
