Fig.5. Analyses of the super-lattice structure formed in the area with the Zr/O atomic ratio 5~7(a~c) SAED patterns obtained by tilting specimen holder to the incident beam parallel to crystal orientation [0001], [11?20] and [?12?10], respectively (The dotted circles in Figs.5a and b shows weak diffraction spots appeared on the sides of the main diffraction spots of α-Zr matrix in the SAED pattern along a certain crystal direction)(d, e) schematic illustrations showing the atomic arrangement and the diffraction intensity of such ordered structure (Z—different heights at which the atoms are located, a—lattice constant)
