ABSTRACT
The processes of amorphization and crystallization of binary and multicomponent melts based on transition metals are considered. A comparative analysis of pre-crystallization structural changes and atomic dynamics in conditions of forced quenching and deep supercooling of metallic melts and other liquid substances, depending on their composition, the size of the atoms, the nature of the interatomic bonds, the presence of eutectics and saddles on the phase diagrams of states is carried out. Hydrogenation of the melts introduces additional specificity on the flow of pre-crystallization processes, affecting the atomic configuration, the modulation of the frequency spectrum and the fluctuations of the band (electronic) structure that determines the specificity of vitrification.
