Mössbauer study of the phase distribution of Fe78−xAlxSi9B13 powder

Abstract In this work, by using X-ray diffraction, magnetization and Mossbauer measurements, magnetic and structural properties of Fe 78− x Al x Si 9 B 13 ( x =10, 20, 30) have been studied. These three sets of specimens in nominal composition Fe 78− x Al x Si 9 B 13 were produced by mechanically processing blended Fe, Al, B and Si powders, using different times in the range from 2 up to 300 h. Mossbauer spectra show a strong line broadening and were fitted by considering Gaussian distributions of hyperfine fields. The crystalline phase present in the spectra was identified as α-Fe. Magnetic hyperfine data are discussed in conjunction with X-ray diffraction and magnetic measurements.
