Hydrogenation of Deeply Cooled Melts as an Effective Method for Amorphization and Control of the Structure of Alloys Based on d-Metals

Processes of amorphization and crystallization of binary and multicomponent melts based on transition metals are studied. Comparative analysis of the pre-crystallization structural changes and of the atomic dynamics under the conditions of forced quenching and deep supercooling of metallic melts is performed. It is shown that hydrogenation of the melts introduces specific features into the occurrence of the pre-recrystallization processes by affecting the atomic configuration, the modulation of the frequency spectrum and the fluctuation of the energy-band (electron) structure determining the vitrification and the coherent nanocrystallization with combination of crystal clusters and clusters with noncrystallographic symmetry.
