| Abstract Scope |
Owing to the vast compositional space, high entropy alloys (HEAs) open a new path in the development of new materials for molten salt reactors.
In this work, high-throughput screening route are used to target compositions with the desired microstructural characteristics via numerical design tools using Thermo-calc and the TCHEA5 thermodynamic database in order, to produce alloys using laser additive manufacturing technologies (Direct Energy Deposition process and a hybrid powder/wire laser innovative process). Once fabricated, the corrosion resistance of these alloys has been tested in a salt molten environment.
The microstructural characterisations by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) has allowed to suggest interesting alloy compositions for the targeted application. |
