Nanocrystal formation in homogeneous and heterogeneous amorphous phases

This review describes the current state of research on the formation of a nanocrystalline structure in amorphous alloys under thermal and deformation effects. The processes of forma-tion of nanocrystals in homogeneous and heterogeneous amor-phous structures (nanoglass) are considered. Changes in the magnetic and mechanical properties during the formation of a composite amorphous-nanocrystalline structure with different structural parameters are analyzed. The possibility of amor-phous phase rejuvenation from a partially crystalline structure under cryogenic thermocycling treatment is shown.
