Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ВЫСОКОТЕМПЕРАТУРНЫЕ ПРЕВРАЩЕНИЯ -- РЕДКОЗЕМЕЛЬНЫE МЕТАЛЛЫ Аннотация: The study into the relationship between the laws of structure formation in metallic melts and the properties of collective ion vibrations is continuing. The phase transition temperatures are found from the Lindemann criterion, where the root mean square amplitude of ion vibrations about a center of equilibrium is compared to the properties of the distribution of such centers. In a liquid phase, the vibration amplitude can decrease with increasing temperature Полный текст |
