SYMPOSIUM 18: Ultra-High Temperature Ceramics

Ultra-high temperature ceramics (UHTCs) are materials of interest for use in extreme environments that are beyond the capabilities of other materials. Some proposed applications for UHTCs include scramjet engine components, leading edges and thermal protection systems for hypersonic vehicles, plasma facing materials in nuclear fusion reactors, solar power concentrators, fuel forms in nuclear fission reactors, and others. Challenges exist for UHTCS and limit near-term use, which include thermal/chemical stability in extreme environments, the ability to be formed into complex shapes, thermal shock resistance, irradiation resistance, and damage tolerance. For such extreme environment applications, advances in the understanding of structure-property relations and performance are needed.

This symposium will focus on design, processing, structure-property relationships, thermal and mechanical properties, oxidation resistance, machining, joining, and stability of UHTCs and UHTC composites, both from fundamental and application-oriented perspectives.

Proposed Session Topics
  • New materials and novel processing methods for bulk, coatings, thin films, fibers, and/or composites
  • Precursors for powders, coatings, and matrix or fibers of composites
  • Processing-microstructure-property relationships of existing or new systems
  • Bulk ceramics, thin films, coatings, fibers, and composites
  • High entropy UHTCs
  • Characterization methods and lifetime assessment
  • Methods for improving damage tolerance, oxidation behavior, and thermal shock resistance
  • Response in extreme environments (irradiation, ultra-high temperature, etc.)
  • Simulation and theory for predicting stability or behavior under extreme environments
