Extended Data Figure 1: Statistical binomial frequency distribution analysis results for the APT tip.
From: Metastable high-entropy dual-phase alloys overcome the strength–ductility trade-off
The statistical analysis shows that the tip has an overall composition of Fe48.6Mn27.6Co11.3Cr12.3 (at%). The binomial curves obtained from the experiments match the curves corresponding to a total random distribution. The quality of the fit was quantified using several parameters, as listed in the key. nd is the number of degrees of freedom for a given ion. The values of the normalized homogenization parameter μ for all four elements are close to 0, confirming the random distribution of elements in the DP-HEA.
