| Abstract Scope |
Designing materials for extreme environments necessitates characterization of candidate materials under environments similar to operating conditions. In the case where elevated temperatures are so extreme, contactless methods are ideal to minimize reactions between the sample and experimental environment. Aerodynamic levitation with laser heating is a contactless method that uses a controlled gas stream to “levitate” the sample, which is then heated by a laser to extreme temperatures (~2800 °C). A host of in-situ characterization methods can then be applied, including machine vision, spectroscopy, and X-ray/neutron diffraction to investigate the structure-property evolution with temperature. These characterization methods were applied to compositionally complex rare earth titanate pyrochlores, a novel material system for environmental barrier coating applications, to elucidate the relationship between thermophysical properties and atomic structure. Aerodynamic levitation with laser heating is a powerful platform, unlocking temperature ranges not previously accessible, to understand material structure-property relationships at relevant conditions. |
