| Abstract Scope |
Refractory alloys are rapidly growing in prominence due to their exceptional strength retention at high temperatures. However, their correspondingly high ductile to brittle transition temperature (DBTT) limits both their manufacturability and applicability in structural components. Methods such as powder-based processing and tailored thermal treatments in controlled environments have made great strides in mitigating this limitation. However, achieving synergetic effects and successfully translating these improvements to bulk properties remains a significant challenge. In contrast, conventional processing routes, such as thermomechanical methods, have received comparatively less attention due to the high reactivity of refractories with air, despite their potential to utilize existing industrial equipment in the implementation of a solution. In this study, we present an approach that uses existing industrial methods to thermomechanically process a bulk refractory above its oxidation temperature by coupling mechanical deformation with a tailored environment. The underlying mechanisms and broader potential of this approach will be discussed. |
