Predicting solid solubility in CoCrFeNiMx (M= 4d transition metal) high-entropy alloys
CoCrFeMnNi is a prototype fcc-structured high-entropy alloy. Numerous efforts have been
paid to strengthen CoCrFeMnNi, by replacing Mn with other elements for an enhancement of
the solid solution strengthening. 4d transition metals, including Zr, Nb, and Mo, are of
interest for this purpose, since they have much larger atomic radii than that of Mn. However,
Nb and Mo are known to have a low solid solubility in fcc-structured CoCrFeNi. Compared to
Nb and Mo, Zr has an even larger atomic radius. The solid solubility of Zr in fcc-structured …
