Poster presented at the 31st Symposium on Fusion Technology (SOFT2020) Virtual Conference
This poster showcases some of the most recent work in collaboration with the University of Oxford on the characterization of reactive sintered borides.
Key aspects of this work showed the complex fractal-like microstructure of RSBs over 5 orders of magnitude and the presence.
Atom probe data enabled revision of the X-ray data models to account for the iron-rich phase being a boron-rich steel-like material with pure Fe inclusions, rather than a mixture of iron borides. No definitive evidence of iron borides was detected by atom probe or TEM.
BCx nuclei present within the Fe-rich phase is indicative of under sintering. WC nuclei were also present in the Fe-rich phase, indicative of the Fe-rich phase acting as a transport for W and C.
