2025 MRS Fall Meeting & Exhibit

Symposium SF09-Materials at High Temperatures—Fabrication, Characterization and Performance

Designing materials for high temperature applications presents numerous challenges in fabrication, characterization, and performance. Behavior can change dramatically from room temperature to high temperature. Solid state chemistry, surface chemistry, phase changes, and microstructural evolution must be understood and controlled. These factors place additional constraints on materials in addition to baseline performance requirements for mechanical strength, thermal stability, and chemical compatibility. A holistic understanding of high temperature performance is critical for advancing wide-ranging applications including gas turbines, high-speed flight, aerospace propulsion, concentrated solar energy, and fusion-based energy.
This symposium will include discussions of fabrication, characterization, and testing of high temperature materials, including ultra-high temperature ceramics (UHTC), refractory metals, high temperature alloys, and ceramic matrix composites (CMC). Specific emphasis will be placed on understanding the performance of materials at/near their service temperature, whether evaluated directly with high temperature measurements, by linking low temperature characterization to high temperature performance, or by evaluation via computational methods. Performance is broadly defined to include mechanical, thermal, chemical, and optical (if applicable) performance and the underlying physical, thermodynamic, microstructural, and chemical mechanisms contributing to performance. Discussion of material synthesis, fabrication, and processing techniques are welcome, particularly as it relates to control of high temperature properties. Investigations of links between fundamental properties (structural, chemical, etc.) and material performance (mechanical, thermal, etc.) are encouraged. Contributions highlighting in-situ and/or high temperature testing are also encouraged.

This symposium is intended to provide both a forum for discussing advancements and challenges in the field of materials for extreme conditions and a networking opportunity to connect researchers across the build, characterize, and test spectrum to build fruitful interdisciplinary collaborations.

Topics will include:

Materials under Extreme Conditions and Environments
Frontiers in Metals Research
High Temperature Material Testing
High temperature Material Fabrication
Characterization; In Situ methods
3D Printing
Materials for Aerospace and Energy Applications
Mechanical Properties at High Temperatures
