Mössbauer Spectrometry in FeMoCuB-Type Nanocrystalline Alloys

Abstract

The applicability of the Mössbauer spectrometry to the study of Fe 91−x Mo 8 Cu 1 B x (x = 12, 15, 17) nanocrystalline alloys prepared by controlled annealing of ribbon-shaped amorphous precursors is demonstrated. Differences between both surfaces of the ribbons are pointed out to be due to preparation conditions. Conclusions from the Mössbauer spectrometry are supported by diffraction of synchrotron radiation, X-ray diffraction, and atomic field microscopy investigations.

Crystallization of NANOPERM-type amorphous alloys

“…Differences between air-and wheel-sides of the as-quenched Fe 79 Mo 8 Cu 1 B 12 specimen were revealed by AFM, CEMS, and diffraction of synchrotron radiation [6]. The air-side presented a smooth surface texture consisting of only few extensions from the ribbon plane while the wheel-side exhibited a wavy surface with notably more protrusions on it.…”
