THE STRUCTURAL AND TOPOLOGICAL HEREDITARITY UPON CRYSTALLIZATION OF NEAR-EUTECTIC ALLOYS

A new representation of a heterogeneous long-range ordered structure of metal melts consisting of "liquid" and "solid" component atoms mixture has been formulated. The elements of a super-high level structure that are directly associated with a quasicrystalline liquid phase structure have been revealed. Like any solid, they are caused by distortion of long-range order in its "quasilattice" made up by "liquid" component atoms at the temperatures exceeding their melting point. Upon crystallization, these structural elements convert excess phases dendrites into macroscopic spherical formations that reflect a "polygrain" melt structure, its topology, and unique "genetic code" acquired during the transfer of layout topological hereditary information from a melt to a solid.
