The glass-forming ability (GFA) of an Fe76Si9B10P5 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 Fe76Si9B10P5 BMG was selected because it is the simplest Fe-rich BMG belonging to Fe-metalloid type with the greatest sample dimensions. A possible reason for the presence of intermediate equilibrium phases to degrade GFA of the Fe76Si9B10P5 was discussed. The results revealed that the Fe76Si9B10P5 BMG is characterized by near eutectic composition in the Fe-rich Fe-Si-B-P quaternary system and by the simultaneous presence of Fe3P and absence of Fe2B phases in equilibrium at a range below the solidus- to the glass-transition temperatures. The analysis of Fe76(Si,B,P)24 alloys for equilibrium phases revealed that the Fe2P phase can degrade GFA of the Fe76Si9B10P5 BMG.
