摘要：

Amorphous structures of liquid-quenched Fe90Zr7B3 and ion-bombarded SiC were studied using modem electron diffraction structure analysis techniques. From a reverse Monte-Carlo (RMC) structural. simulation on the experimental atomic pair distribution function (PDF) of amorphous Fe90Zr7B3, "nano-scale phase separation" was found to occur in this structure with spatial distributions of body-centered cubic-like, icosahedral and trigonal prism clusters. In amorphous SiC, the network includes not only heteronuclear (Si-C) bonds but also homonuclear (Si-Si and C-C) bonds. The ratio of homonuclear to heteronuclear bonds changes due to structural relaxation. (C) 2003 Elsevier Science B.V. All rights reserved.
