This report summarizes the activities of the Materials Sciences Program in the Oak Ridge National Laboratory (ORNL) Metals and Ceramics Division for the period July 1, 1987 to April 30, 1989. The program is directed at uncovering principles for the scientific design of materials. The efforts emphasize three classes of materials: high-temperature metallic alloys based on intermetallic compounds, structural ceramics, and radiation-resistant alloys. The principal elements of Materials Science and Engineering --- synthesis/processing, characterization, properties, and performance --- are incorporated in all of these programs to achieve a full understanding of the relationships among the elements. A first-principles theory provides understanding of the structure of alloy systems. Surfaces and interfaces of ceramic systems are investigated through ion beam and molecular beam epitaxy activities. Major emphasis is placed on structural characterization capabilities to furnish the link between processing and performance.
