摘要：

The atomic structure of liquid-quenched amorphous Al90FexCe10-x(x = 5,7) was studied by pulsed neutron and x-ray scattering. The atomic pair-density function determined by pulsed neutron diffraction indicates that a significant portion of Al-Fe distances is anomalously short, while some part of the Al-Al distances is anomalously long. Both neutron and x-ray scattering showed the presence of a prepeak in the structure factor. These results suggest that a strong interaction between A1 and Fe modifies the structure of this glass, leading to chemical and topological short-range ordering. © 1990, Materials Research Society.
