In the past decades, high-entropy alloys (HEAs) have drawn great attention due to their unique single-phase microstructures and outstanding mechanical properties as structural materials. Vast efforts have been devoted to finding single-phase HEAs from the aspect of experiments. However, targeting single-phase HEAs systems and compositions is still a challenge. In the present work, high throughput calculation method which is based on the calculation phase diagrams (CALPHADs) is performed to accelerate the pace of finding single-phase HEAs compositions computationally and investigating the HEAs systems in detail. A compositional mapping of the several HEAs system are conducted under certain criteria with different step sizes. In addition, these thermodynamics calculations will be discussed with the formation rules. Various of experiments are conducted for the verification of the single-phase prediction.
