Predição de formação de solução sólida de ligas de alta entropia por Hume-Rothery

Solid solution formation (SSF) is of main concern in high-entropy alloys (HEAs). The more ready-to-implement approach to predict SSF is the Hume-Rothery’s (H-R). Therefore, this paper presents four parameters and their acceptance criteria to evaluate HEAs in what refers to SSF. Furthermore, AlCoCrFeNi alloy was subjected to SSF prediction framework based on H-R. The results show that the alloy does not form a solid solution based on H-R, which disagrees with several reports in the literature. Therefore, the framework should be aggregated with other parameters to predict the SSF of this alloy.
