The work is devoted to the study of the laws of the formation of a hydride rim in E110 zirconium alloy claddings during gas-phase hydrogenation. The problem of hydrogen penetration and accumulation and the subsequent formation of hydrides in the volume of zirconium cladding tubes of water-cooled power reactors remain relevant. The formation of brittle hydrides in a zirconium matrix firstly, leads to a significant change in the mechanical properties, and secondly, can cause the destruction of the claddings by the mechanism of delayed hydride cracking. The degree of the hydride’s effect on the mechanical properties of zirconium cladding is mainly determined by the features of the hydride’s distribution and orientation. The problem of hydride rim formation in zirconium alloys with niobium is quite new and poorly studied. Therefore, the study of hydride rim formation in Russian zirconium alloy is important and necessary for predicting the behavior of claddings during the formation of the hydride rim.
The paper presents National Research Tomsk Polytechnic University (TPU) and its partner-organizations experience in development and delivery of educational programme within the topic: “In situ techniques of synchrotron investigation of multilayered functional structures with unique parameters and properties designed with beam-plasma surface engineering”. The unique features of the programme are discussed, as well as specifics of its realization and factual outcomes — educational aims and learning outcomes. The educational programme is unique representation of experience of research and educational organizations. The programme specifics include its realization in the format of hybrid and blended teaching and learning in new conditions of pandemics.
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.
