Topologically Designed and Resilient Ultrahigh Temperature Ceramics
Ultrahigh temperature ceramics are a class of materials with exceptionally high melting temperatures. Consequently, they hold great promise for extreme environment applications that include hypersonic flight, nuclear fusion reactors, and concentrated solar power. However, they are brittle at low temperatures, which negatively impacts functionality. Conversely, these materials deform too much at ultrahigh temperatures. Usually, one of these properties can be improved at the expense of the other, making optimization difficult. This Designing Materials to Revolutionize and Engineer our Future (DMREF) project will develop a new method to simultaneously improve both the low temperature and high temperature properties of these materials by devising a means to design and manufacture specific crystal structures and unique microstructures. As part of this research effort, the next generation of scientists and engineers will be trained in a cross-disciplinary manner as they work together to bridge different disciplines. This education will be expanded through an active high school and undergraduate summer program that identifies underserved demographics in STEM. Additionally, this project will educate secondary school teachers about materials science, and specifically ceramics, giving them the toolsets to integrate such information into physics, chemistry, and physical science courses dramatically broadening the impact of the science generated.
