Preparation and properties of Fe80−xNixP14B6 bulk metallic glasses
چکیده انگلیسی
Bulk Fe80−xNixP14B6 (x = 20, 30, 40, 50 at.%) glassy alloy rods with the diameters of 1.0-2.5 mm were synthesized by combining fluxing technique and J-quenching technique. The glassy alloy rods were characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC) and vibrating sample magnetometer (VSM). It is found that the range of supercooled liquid region (ΔTx) is 27-32 K. The saturation magnetization of Fe80−xNixP14B6 (x = 20, 30, 40, 50 at.%) bulk glassy alloys gradually decreases from 1.13 T to 0.58 T with increasing Ni content from x = 20 to x = 50. More importantly, the present quaternary FeNiPB bulk metallic glasses (BMGs) shows a significant plastic strain, in particular, the plastic strain of Fe30Ni50P14B6 BMG reaches as high as 11.7%. The corrosion resistance of the present FeNiPB BMGs was studied by weight-loss method, potentiodynamic polarization curves and scanning electron microscopy (SEM). It is shown that the corrosion resistance of the present FeNiPB BMGs in 0.5 M NaCl and 1 M HCl solution increases with Ni content, and further the present FeNiPB BMGs exhibit larger Ecorr values and lower Icorr values, i.e. higher corrosion resistances, than that of stainless steel.
