# hea-bench

> hea-bench — dfieser-hea-bench. Use this tool when you need to calculate and predict the properties of high-entropy alloys (HEAs) and high-entropy oxides, solving problems in materials science and phase prediction. It takes input parameters such as composition and outputs values like mixing entropy, atomic-size mismatch, and VEC. Use hea-bench in research and development contexts where predicting phase formation and stability of complex alloys is crucial.
