X-ray diffraction method has been carried out to study the structure in the equiatomic InPbGaSnCu high entropy alloy in liquid state. Structure factors and pair correlation functions have been analyzed and used to determine the main structure parameters. Existence of shoulder on right hand side of principal peak and its transformation was the main feature of structure factors. Comparison of structure functions and main parameters obtained from them for multicomponent alloy with ones for constituent elements shown that mixing process is related with formation of structural inhomogeneities in liquid state.
Методом лежачої краплi дослiджено поверхневий натяг та густину системи Sn1−xBix iз вмiстом 5, 10 та 15 ат.% Bi в температурному iнтервалi 470–800 K у вакуумi 10 Па. Для отримання експериментальних значень дослiджуваних фiзичних характеристик використовувалась програма DROP. Виявлено, що додавання вiсмуту до олова приводить до зменшення поверхневої енергiї розплавiв системи Sn1−xBix. Також показано, що iснують лiнiйнi температурнi залежностi для коефiцiєнта поверхневого натягу та густини.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
