講演テーマ:Next Generation Ultrahigh Temperature Materials: Oxide-NonOxide Ceramics
講演概要:Next generation ultrahigh temperature materials, which will increase the operating temperature of gas turbines by several hundreds of degrees Centigrade, are likely to draw upon two materials classes, silicon carbide and transition-metal/rare-earth oxides, as well as polymer-derived ceramics that combine Si-N-O-Metals at the molecular scale. The carbides impart resistance to deformation while the oxides provide resistance to oxidation. The silicon carbide fiber, which can be spun into net shapes and then infiltrated with an oxidation resistant matrix, sets the stage for the architecture of these ultrahigh temperature ceramic matrix composites (CMC). The elements of underlying science that couples microstructure design, processing and oxidation behavior with special emphasis on the hafnia-silicon carbide system will be discussed.
