| Abstract Scope |
The limited availability of corrosion- and irradiation-resistant high-temperature alloys significantly hinders the deployment of several promising technologies, including molten salt, fission, and fusion nuclear technologies, which have the potential for substantial societal impact. To expedite alloy development for these applications, we developed a suite of high-throughput techniques encompassing alloy synthesis, corrosion and irradiation testing, characterization, and modeling. These methods were employed to assess the environmental degradation resistances of hundreds of high-entropy alloys based on 3d transition metals and refractory elements. The benefits of using additive manufacturing to accelerate alloy synthesis are highlighted. By integrating these synthesis techniques with novel irradiation and corrosion platforms, we characterized the degradation resistances and utilized them as performance metrics in random forest regressor machine learning algorithms to predict the most resistant alloys. Furthermore, we discuss and compare the detailed characterization of corroded or irradiated industrial alloys produced by both additive manufacturing and conventional casting methods. |
