| Abstract Scope |
High-entropy alloys (HEAs) are of interest in the development of next-generation molten salt-based energy systems for their corrosion resistance and thermal stability. The vast compositional and phase space of HEAs represent an immense opportunity to develop new alloys, but also a significant challenge as current high-temperature electrochemical methods are mostly low throughput. We recently developed a high-throughput method to fabricate HEA compositional arrays using in-situ alloying of elemental powders in a LENS system [Nelaturu et. al., TMS 2020]. In this work we demonstrate a mini-electrode assembly designed to perform high-throughput cyclic voltammetry on a molten salt drop on each point of the compositional array. We also present developments of a data structure with optimized efficiency for storing the large amounts data. This data structure will then be used as input for a feature recognition and categorization machine learning algorithm to automate the high-throughput electrochemical analysis of novel alloys. |
