IWGGCR--4: High temperature metallic materials for application in gas-cooled reactors

International Atomic Energy Agency, Vienna (Austria)

Abstract

At the meeting overviews of current programmes for the development of high temperature materials in Japan, F.R. Germany and the United States of America were presented. Some papers were presented dealing with various aspects of microstructural studies, surface reactions and the changes of microstructure and dimensions due mainly to the associated interfacial material transports, protective surface coatings for HTGR and AGR applications. Other topics presented were mechanical properties of materials and also the influence of materials' properties data on design at temperatures in the creep region where time dependent behaviour must be considered
