Abstract:Zry-4 fuel cladding tubes were exposed in mixtures of oxygen and nitrogen at temperatures of 800–1380 °C. The influence of various flow rates of oxygen and nitrogen as well as specimen height on the weight gain was examined. Metallographic observations were carried out and residual mechanical properties were assessed employing ring compression tests (RCT). The overall weight gain was substantially affected by both the applied flow rates and the height of specimens. The oxidation kinetics in air was assessed ba… Show more
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.
