Thermodynamics of concentrated solid solution alloys (2017, background): “Furthermore, some empirical rules have been determined based on limited number of compositions [16,18,21,22].”
Criteria for Predicting the Formation of Single-Phase High-Entropy Alloys (2015, result): “[16] M. G. Poletti and L. Battezzati, Electronic and Thermodynamic Criteria for the Occurrence of High Entropy Alloys in Metallic Systems, Acta Mater.”
Phase stability of non-equiatomic CoCrFeMnNi high entropy alloys (2015, methodology): “empirical rules [19–26], or ab initio based methods [27,28]), the CALPHAD method provides an optimal balance between efficiency and accuracy.”
Hume-Rothery for HEA classification and self-organizing map for phases and properties prediction (2017, methodology): “Because of the controversial use of e/a values for transition metals (TMs) VEC has often been preferred to study the electron concentration effect on phase stability in HEAs and has been presented by several authors as a key parameter to classify HEAs [14,17,21,24,26].”
