Alloyed powders with combination of (Fe67 Ni33)70 Ti10 B20 at different milling times are obtained.
Structural, magnetic and thermal characterizations are performed by using X- ray diffraction, scanning
electron microscope, energy dispersive X-ray spectroscopy, differential scanning calorimetry, transmission
electron microscopy and vibrating sample magnetometer. It is indicated that the crystallite size is
sharply decreases in the initial stage of milling process and the microstructure tends to nanocrystalline
structure with increasing milling time. A rapid drop in saturation magnetization is observed after 48 h
milling time, while coercivity value attains to a lowest value of about 33 Oe. Heat analysis of the milled
sample at 120 h shows an endothermic peak. The coercivity of the 120 h annealed sample is increased as
compared to the starting powders.
