(a), (b) High-resolution TEM images for t = 0 and 120 min. The size of each image is 154 nm×154 nm. The insets are the corresponding diffraction patterns. (c), (d) Higher-resolution TEM images of the Cu crystal grains in panels (a) and (b). The white arrows indicate different crystal plane orientations. The size of each image is 12 nm×23 nm. Panels (e) and (f) are, respectively, the size distributions of the crystal grains in panels (a) and (b).
