Optimization of Soft Magnetic Properties in Fe-B and Fe-B-Si Amorphous Alloys Obtained by Melt Spinning Method

Soft Magnetic Bulk Glassy Fe–B–Si–Nb Alloys with High Saturation Magnetization above 1.5 T

New Fe-based bulk glassy alloys were synthesized in the (Fe0.75B0.15Si0.10)100−x Nbx system by copper mould casting. The maximum diameter of the bulk glassy alloy rod was 0.5 mm at 1 at%Nb, 1.0 mm at 2 at%Nb and 1.5 mm at 4 at%Nb. No glass transition is observed at 0 at%Nb, but the addition of Nb causes the appearance of glass transition before crystallization. The glass transition temperature ...

Hydrogen Effects on an Amorphous Fe-Si-B Alloy

HYDROGEN interaction with amorphous alloys has Ribbons (,25-mm thick) of amorphous Fe80B11Si9 were been studied extensively due to both scientific and technoused for this research. The ribbons were produced by planarlogical interest. In the framework of a more comprehensive flow casting and were kindly supplied by AlliedSignal Inc. investigation of hydrogen interaction with amorphous and (Parsi...

Effect of Cu Addition on Soft Magnetic Properties of Fe–Zr–Si Amorphous Alloy

The effect of Cu addition on the soft magnetic properties of Fe­Zr­Si amorphous alloy was investigated by X-ray analysis, TEM observation, and B-H curve tracer. As a melt-spun amorphous ribbon sample was annealed above the crystallization onset temperature, very fine ¡-Fe particles smaller than 315 nm were precipitated and uniformly distributed in an amorphous matrix. Cu addition to Fe­Zr­Si am...

ساختار و خواص مغناطیسی آلیاژهای ‍‍CoFeSiB انجماد سریع یافته

The effects of metalloids Si(4-27 at%) and B(5-22 at%) on the structure and magnetic properties of melt spun cobalt based alloys containing 5at% Fe have been studied. XRD results revealed that in non-eutectic ternary CoFeSi and CoFeB alloys, the additions of Si or B, alone can not lead to full amorphization of melt spun ribbons. In quaternary CoFeSiB alloys, the total amounts of Si and B additi...
