PACRIM S16: Advanced Structural Ceramics for Extreme Environments

Structural ceramics are enabling materials for applications that involve extreme environments, such as those associated with nuclear power generation, turbine engines, hypersonic flight, high speed machining, and other demanding applications. The radiation levels, temperatures, heat fluxes, wear/abrasion, and other environments encountered in these applications exceed the capabilities of existing materials. Hence, new ceramics and composites are needed. Some critical challenges include thermal/chemical stability, complex shape forming, thermal shock resistance, radiation tolerance, and damage tolerance.

This symposium will focus on computational and experimental studies in areas such as design of new materials, synthesis, processing, structure-property relationships, thermal and mechanical properties, oxidation resistance, machining and joining, and stability of advanced structural ceramics, both from fundamental and application-oriented perspectives.

Proposed sessions

• High entropy ceramics
• MAX phases, MXenes, and related compounds
• Oxide-, carbide-, boride-, and nitride-based ceramics and composites
• New precursors for powders, coatings, and matrix or fibers of composites
• Novel synthesis and processing methods (bulk, coatings, and thin films)
• Materials design, new compositions, and composites
• Structure-property relationships at room and elevated temperatures
• Novel characterization methods and lifetime assessment
• Methods for improving damage tolerance and resistance to oxidation, radiation, thermal shock, etc.
