Presolidification Changes in the Structural–Dynamic Characteristics of Glass-Forming Metallic Melts during Deep Cooling, Vitrification, and Hydrogenation

The amorphization and solidification of binary and multicomponent transition-metal-based melts are considered. The presolidification structural changes and the atomic dynamics in metallic melts and other liquid substances that occur during forced quenching and deep supercooling are analyzed and compared as functions of their composition, the atomic size, the character of interatomic bonds, and the presence of eutectics and compounds in phase diagrams. The hydrogenation of a melt changes presolidification processes, affecting the atomic configuration, the modulation of a frequency spectrum, and the fluctuations of band structure (which determines the character of vitrification).
