Statistic volume distribution of the L1₂ nanoprecipitates and quantitative lattice misfit and lattice strain in the HEAs. a) Normalized percentage with respect to the single precipitate volume, the inset shows the overall volume fractions of L1₂ precipitates. b) Lattice parameter and lattice misfit of the L1₂ and fcc phases. The lattice misfit (ε) is calculated using the equation ε = 2(a _L12 − a_fcc )/(a _L12 + a_fcc ), where a _L12 and a_fcc are the lattice parameters of the L1₂ and fcc phases, respectively.^[ ³⁶ ^] c) Local strain distribution map and corresponding phase distribution map of the 3Al‐HEA and 7Al‐HEA. d) 1D strain distributions along the arrows in (c).
