Modeling High Entropy Alloys' Mechanical Property through Natural Language-Derived Descriptors

Abstract

Processing treatments of alloys, despite being influential to alloy properties, are often neglected in machine-learning aided alloy designs due to the difficulties in expressing this information. We investigated the expressiveness of transformer embeddings through synthesized annealing processing treatment text and verified that embeddings could be utilized to reconstruct the processing parameters of alloys effectively with an R2>0.99. We then utilized the vector representations of alloys' processing treatment descriptions as descriptors to model high-entropy alloys' hardness and achieved a 20% improvement in prediction, verifying that natural language-derived descriptors of processing treatment information could be utilized to improve prediction of alloy properties.
