Abstract . Medium- and high-entropy alloys (M/HEAs) mix several principal elements with near-equiatomic composition and represent a model-shift strategy for designing previously unknown materials in metallurgy1 , 2 , 3 , 4 , 5 , 6 , 7 , 8, catalysis9 , 10 , 11 , 12 , 13 , 14and other fields15 , 16 , 17 , 18. One of the core hypotheses of M/HEAs is lattice distortion5 , 19 , 20, which has been investigated by different numerical an...
