Rational design of amorphous alloys from the viewpoint of elasticity can be achieved through machine learning methods to generate optimized elastic predictive models, which have been successfully verified and demonstrate the potential to accelerate composition screening and property optimization of amorphous alloys.
Rational design of amorphous alloys from the viewpoint of elasticity can be helpful as it offers close correlations with glass forming ability (GFA), thermal stability, mechanical properties and so on. Here, by separately employing composition and structure descriptors as input, we successfully optimized, generated and interpreted the elastic predictive models via various machine learning (ML) approaches, which exhibit distinct advantages of high accuracy, simple operation, wide applicability and good interpretability relative to that of previously reported elastic models. Meanwhile, the performances of our developed elastic models were well verified via GFA and plasticity prediction in two ternary amorphous alloy systems. Finally, based on the above improved elastic models, we proposed a general framework for rational design of amorphous alloys using four steps strategy. Our results demonstrate the great potential to accelerate the composition screening and property optimization of amorphous alloys. CO 2022 Published by Elsevier Ltd.
