Description
Summary:The individual characteristic properties of local atomic ordering of structure forming in Fe83M17 (M: C, B, P) metallic glass have been indicated by a computer simulation method. It is proved that carbon atoms 'prefer' to take up the interstitial positions in atomic configurations based on a distorted octahedron and trigonal prism while boron atoms tend to occupy the centres of a distorted Archymedian antiprism. Phosphorus atoms are able to take up both the interstitial and the substitutional positions and the short-range ordering around them is mainly icosahedrical. The interrelationship between the atomic structure of Fe83M17 (M: C, B, P) amorphous metallic alloys and their vitrification ability has been determined.
