Formation of a Intermediate Order in Metallic Glasses and a Long Order in Nanocrystalline Alloys with Allowance for the Character of Binding and the Transformation of the Short Order in a Melt

Аннотация

The results of studying the formation of short- and intermediate orders in amorphous alloys and a long-range order in nanocrystalline alloys in quenching of metallic melts show that the structures of metal atom groups in both states consist of both icosahedral and helicoidal packings, which coherently combine crystalline and noncrystalline coordinations due to fractional symmetry.
