Abstract Scope |
In this work, representative theories for predicting simple solid solution high-entropy alloys (HEAs) are reviewed. The models are first classified into two categories - parameter based and free-energy based, according to their core strategy. Then, one hundred distinct HEAs are used to benchmark the accuracy and the degree of unbalance of the models. Based on careful analysis of the results, five factors that impact the accuracy of models are pointed out and discussed. These include two global factors and three alloy-specific factors. Finally, future directions to better assess these theories and to develop more accurate models are suggested. |
