Аннотация:Asingle structural model for the experimentally determined succession of phase transitions between cubic -,-, - and -modifications of Mn, in which the lattice constants of the modifications decrease with the temperature growth is suggested. The model is based on the definition of the Mn phases as successive periodic approximants of a linear substructure of a four-dimensional analog of an icosahedron. The model seems to be appropriatefor an adequate description of structural transformations in close-packed metals and of variation of their structure-sensitive properties under heat treatment.
