(color online) Microstructures of the samples with the to-be-measured random grain boundaries indicated by long white arrows. Deformed temperature: (a), 1100 °C; (b), 1000 °C; (c), 900 °C; (d), 800 °C; (e), 700 °C. Three annealing twins are indicated by short red arrows in panel (b) to illustrate their morphological characteristics.
