E. Matsubara et al., Structural study of amorphous Fe70M10B20 (M = Zr, Nb and Cr) alloys by X-ray diffraction, MAT SCI E A, 312(1-2), 2001, pp. 136-144
The local atomic structures in the amorphous Fe70Zr10B20, Fe70Nb10B20 and F
e70Cr10B20 alloys with different DeltaT(x) were studied by the ordinary X-r
ay diffraction, anomalous X-ray scattering (AXS) measurements and EXAFS ana
lyses. The essential features of the atomic structures resemble in these am
orphous alloys. Only the difference in the local atomic structure is a dist
orted shape ;of the triangular prism due to the size difference between Fe
and M. From the correspondence of the size difference with DeltaT(x) and th
e study of the crystallization process by the DSC measurements and the X-ra
y diffraction method, we conclude that the difference of their thermal stab
ility is closely related with the difficulty of rearrangements of the prism
s during crystallization. (C) 2001 Elsevier Science B.V. All rights reserve
