a The XRD patterns of the cold-rolled and annealed EHEAs comprising the FCC and BCC phase. b The chemical concentrations of Al and Co elements in the lamellar structure of the EHEAs. The center and radius of the semicircles represent the average and standard deviation of concentrations. c The inverse pole figures of the FCC and BCC phase in a lamellar and/or near-equiaxed microstructure. d The grain boundary maps highlighting the FCC/BCC interfaces with the K-S orientation relationship displayed in red. The statistical result of the length of the interfaces with the K-S orientation relationship (measured in μm) over the total detection area (measured in μm2) in the annealed EHEAs. The IPF maps and grain boundary maps of the CR EHEAs are shown in Supplementary Fig. 5.
