Fig. 3: Microstructure of the matrix.

a HRTEM image of Cu-18Zn-8Al-0.3V-0.3Si single-crystal alloy before deformation. The inset shows the corresponding selected area electron diffraction (SAED) and Geometric Phase Analysis (GPA) results. b HRTEM image of the 18R-LPSO structures within the distortion regions. The IFFT result shown in the illustration clearly reveals the periodic stacking of the 18 R structure. To further confirm its crystal structure, the corresponding FFT analysis displays an interaxial angle of 89.93°. The GPA result indicates the presence of significant lattice distortion in this structural region.
