Abstract

The local atomic structures in the amorphous Fe₇₀Zr₁₀B₂₀, Fe₇₀Nb₁₀B₂₀ and Fe₇₀Cr₁₀B₂₀ alloys with different ΔT_x were studied by the ordinary X-ray diffraction, anomalous X-ray scattering (AXS) measurements and EXAFS analyses. The essential features of the atomic structures resemble in these amorphous alloys. Only the difference in the local atomic structure is a distorted shape of the triangular prism due to the size difference between Fe and M. From the correspondence of the size difference with ΔT_x and the study of the crystallization process by the DSC measurements and the X-ray diffraction method, we conclude that the difference of their thermal stability is closely related with the difficulty of rearrangements of the prisms during crystallization.
