| Abstract Scope |
The emergence of high-entropy alloys (HEAs) represents a shift in alloying strategies, offering the ability to customize material performance through tailored chemical compositions. In nuclear applications, materials must withstand challenging conditions including high temperatures, corrosive environments (such as molten salts, liquid metals, and gases), and exposure to neutron radiation. This study integrates HEA alloy design principles with advanced manufacturing techniques to develop new materials suited for nuclear applications. Using CALculation of PHAse Diagrams (CALPHAD) simulations, multiple refractory HEAs were designed and optimized. These alloys were fabricated using electric field assisted sintering. Comprehensive characterization involved multiscale microstructural analysis and mechanical testing to assess their suitability. The microstructure of the developed refractory HEA showed BCC phase matrix with uniformly distributed Ti- and Al-rich precipitates in the matrix. Selected alloys underwent testing for resistance to molten salt corrosion, focusing on studying the influence of microstructural features like second-phase particles and precipitates in detail. |
