| Abstract Scope |
In nuclear applications, the component materials are expected to experience high temperatures, corrosive environments (molten salt, liquid metals, and gases), and neutron fluences. Economics and safety dictate that the component often must operate in these aggressive conditions for decades without failure. The most important properties from a materials design standpoint are robust mechanical properties including tensile strength, creep and fatigue resistance, microstructural stability, corrosion resistance, and radiation damage resistance. In this study, multiple refractory high entropy alloys are developed and manufactured using electric field assisted sintering. The as-processed alloys consisted of a primary BCC phase, which is predicted to by CALculation of PHAse Diagrams (CALPHAD) simulations to be stable in the material over a broad temperature range up until the melting point. Mechanical testing and molten salt corrosion testing were performed on the material to understand the properties of the material. |
