a The inverse pole figures of the FCC and BCC phase in the deformed AC and P2 EHEAs. b Volume fraction of the FCC and BCC phase and the fraction changes of the FCC phase after tensile deformation in the EHEAs. c High-resolution transmission electron microscopy (HRTEM) images of the deformed P2 EHEA. The inset shows the corresponding Fast Fourier transformation (FFT) pattern. d Enlarged view of the white dotted rectangular area in c. The inset is a schematic diagram of the stacking fault. e Enlarged HRTEM images of region A, B, and C in (c). f, g The distribution of the measured angle of α, β, respectively.
