Hardness versus average grain size for our current CoCrNi and CoCrNi-O alloys. Error bars represent standard deviation. Literature data of Ni42,43,44,45, NT-Ni46, NiMo13, NiCo47, and CoCrNi48,49,50,51,52,53,54,55,56,57 alloys are included for comparison. The solid lines are fitted by Hall-Petch relation (H~ \({d}^{-\frac{1}{2}}\)). The dash lines show the inverse Hall-Petch softening (H~d). The fitting parameters for the Hall-Petch and inverse Hall-Petch relationships are summarized in Supplementary Table 2. Source data are provided as a Source Data file.
