Abstract Scope |
The implementation of ceramic matrix composites (CMCs) in next-generation fusion reactors hinges on the development of robust interphases that can resist extreme environments, including high temperatures, corrosive conditions, and radiation exposure. In this work, I will show how by using in-situ scanning and transmission electron microscopy (SEM and TEM) we can better understand the behaviour of nanoscale interphases in SiC-based CMCs across a range of operational conditions. I will first introduce our methodology for characterising interphases from ambient to elevated temperatures using SEM in-situ micromechanics. Subsequently, I will show how TEM in-situ characterisation and testing, reveals the impact of radiation damage on the microstructure and mechanical performance of these materials. Our findings contribute to the fundamental understanding necessary for the design of durable interphases in fusion-relevant environments. |
