T4S7: Materials for Extreme Environments: Ultra-high Temperature Ceramics (UHTCs) and Nanolaminated Ternary Carbides and Nitrides (MAX Phases)

Register for 11th CMCEE

 

Ceramic technologies for sustainable development

 

Ultra-high temperature ceramics (UHTCs) and nanolaminated ternary carbides and nitrides (MAX phases) are potential materials for use in extreme environments, such as scramjet engine components, leading edges and thermal protection systems for hypersonic vehicles, and cladding materials in generation IV nuclear reactors. However, thermal/chemical stability in extreme environments, ability to form into complex shapes/sharp edges, thermal shock resistance, irradiation resistance, and damage tolerance are critical challenges limiting near-term industrial applications of these materials. For such extreme environment applications, new advances in understanding structure-property relations and improving performances are needed, which require developing new approaches for improved thermal shock resistance, thermochemical stability, damage tolerance and machinability, and discovering new materials to ensure an enormous leap forward in performances. This symposium will focus on design, processing, structure-property relationships, thermal and mechanical properties, oxidation resistance, machining and joining, and stability of UHTCs, and MAX phases both from fundamental and application-oriented perspectives. 

 

Proposed session topics:

  • New precursors for powders, coatings, and matrix or fibers of composites
  • Structure-property relationships of existing systems
  • Materials design, new composition, and composites
  • Novel processing methods (bulk, coatings, and thin films)
  • Novel characterization methods and lifetime assessment
  • Methods for improving damage tolerance, oxidation, and thermal shock resistance
  • New methods for joining and machining of components
  • Structural stability under extreme environments (irradiation, ultra-high temperature)
