Приведены результаты экспериментальных исследований церия при высоких скоростях и наносекундных длительностях воздействия. Проведено исследование изоморфного фазового перехода при ударном сжатии. Определена откольная прочность церия. Обнаружена аномальная сжимаемость церия при динамическом нагружении. Показано затухание волны напряжения при воздействии сильноточного электронного пучка за счет диссипации энергии при фрагментации и двойниковании.Работа выполнялась при финансовой поддержке гранта РНФ 17-11-01053.
Abstract. The article is devoted to the study of the behavior of a titanium alloy under conditions of high-speed penetration at a speed of approximately 2.0 km / s. It is shown that in the target during penetration, three penetration zones are observed that differ in the mechanisms of plastic deformation and fracture.
Abstract. The article is devoted to the study of the features of dynamic deformation and destruction of porous iron under the influence of a cumulative "knife". It is shown that ultrafast action on the target led to intensive structure formation of porous iron at the mesoscale.
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.
