Iron-based amorphous alloys have attracted a growing interest due to their potential in the application of magnetic coil production. However, the magnetization of this kind of material is usually low due to the lack of long range ordering and high...
The crystallization processes of Fe83.3+xB7-x,P9Cu0.7 (x = 0 to 2.5 at%) amorphous alloys were thermodynamically assessed using Thermo-Calc software with TCFE7 database for Fe-based alloys. The analysis of the alloys for a primary crystallization ...
The glass-forming ability (GFA) of an Fe26Si9B10P5 bulk metallic glass (BMG) was evaluated thermodynamically with commercial software, Thermo-Calc, with Fe-base database, TCFE7 by utilizing its best ability to deal with equilibrium phases. The Fe2...

Effects of an addition of Si and P into amorphous Fe85.2B14Cu0.8 based soft magnetic alloys were investigated in boric-borate buffer solution. The addition of P decreased the passive current density effectively. Substituting Si for Pin Fe85.2SixB9...
High-entropy alloys (HEAs) with an atomic arrangement of a hexagonal close-packed (hcp) structure were found in YGdTbDyLu and GdTbDyTmLu alloys as a nearly single hcp phase. The equi-atomic alloy design for HEAs assisted by binary phase diagrams s...
