Abstract：To explore the preparation of oxygen in the atmosphere affect the performance of Fe-based amorphous alloy,the Fe40Ni40P14B6 bulk amorphous alloy was prepared by Fluxing purification and J-quenching rapid solidification in argon,air and oxygen respectively.The vitrification forming ability,thermal stability,magnetic properties and mechanical properties of the samples prepared under different atmospheres were compared.The results show that the maximum diameters of Fe40Ni40P14B6 bulk amorphous alloy rods prepared in argon,air and oxygen atmospheres are 2.0,1.5 and 1.0 mm,respectively.With the increase of oxygen content in the preparation atmosphere,the vitrification forming ability of Fe40Ni40P14B6 alloy decreased gradually.The transition temperature(Tg)and initial crystallization temperature(Tx)of the glass gradually decrease,and the thermal stability decrease.The saturation magnetization gradually increased from 0.74 T in argon to 0.80 T in oxygen.The compressive strength decrease slightly,but the plastic strain increase slightly.
