| Abstract Scope |
Ultra-high temperature ceramics (UHTCs) are prominent candidates for enabling critical advancements in aerospace and sustainable power production. Recent investigations demonstrate their exceptional thermophysical properties, robust structural performance under extreme conditions, and promising high-entropy effects. However, characterization techniques that yield performance-relevant properties are ineffective at systematically exploring their vast compositional space and lack the throughput necessary to survey operating temperatures. By developing a geometry (slack-chain) capable of sequentially testing samples of discrete compositions and incorporating laser heating to span the temperature domain, this work seeks to increase the data acquisition rate of high-temperature tensile testing by over 10x. Preliminary slack-chain results produce statistically meaningful tensile datasets, an advantage that is especially significant for materials prone to flaw-dominated deformation behavior. Additionally, CO2-laser-heated tensile testing to 1800°C with in situ temperature and strain diagnostics is demonstrated and underscores the promise of laser heating as a noncontact heat source with rapid thermal cycling capabilities. |
