(a,b) HRTEM images of two typical areas of the 15-h-annealed sample and (c,d) their corresponding strain maps by GPA, where the colors represent different strain levels. (e,f) The enlarged images of areas I and II in (a), respectively, with the insets showing their respective electron diffraction patterns. (g,h) Intensity profile of the FFT patterns of the areas inside the red circles (red curves) and blue circles (blue curves) of (a,b), respectively.
