چکیده
|
In the present research, rapidly solidified fe85.3b11p3cu0.7 ribbons were prepared by melt spinning process. the microstructural variation as well as magnetic properties of the asspun and annealed ribbons were characterized by xray diffraction (xrd), transmission mossbauer spectroscopy and alternating gradient field magnetometer (agfm). the results show two separated distinct exothermic peaks during heating resulting from the phase transition from amorphous to alpha;fe and then to fe3b, respectively. the study of magnetic properties in the amorphous and nanocrystalline states revealed that annealing the amorphous ribbons at 440˚c for 10 minutes gives rise to a significant increase in saturation magnetization (220 emu/g) which makes this alloy a good candidate for power applications.
