a, b High-resolution transmission electron microscopy (HRTEM) image at the phase interface, oriented to the [001]α zone axis (a) and [1\(\overline{1}\)0]α zone axis (b), respectively. c, d Selected area electron diffraction (SAED) at the phase interface correspond to Fig. 5a and b, respectively. e The microstructure of the S-4 alloy at the strain of −5% along the loading direction, the white dashed line indicates the phase boundary (PB). f The HRTEM image at the shear band area of the H phase, insert is the SAED at the H phase, oriented to the [010] zone axis. The local shear band is formed after large compressive deformation. g Intensity profile along with LD in A and B zones marked in Fig. 5f.
