Fe82Nb6B12 alloy was synthesized from the elemental powders by a planetary
high-energy ball mill, at room temperature, using different milling times a
nd different surfactants. The products were measured by X-ray diffraction,
magnetic thermogravimetry, vibrating sample magnetometer, and Mossbauer spe
ctroscopy. Amorphization was observed from the X-ray diffraction on a sampl
e ball milled for about 220 h using 595 rpm and cyclohexane as surfactant.
Nevertheless, using the same conditions without surfactant, only the bcc Fe
was found. The results are compared with data for rapidly quenched materia
