(a) HRTEM micrograph of the striated structure viewed in the [311]β direction. The inset shows an FFT image from the corresponding HRTEM image. (b) Characteristic zones corresponding to the perfect β phase (b1), those giving quasi-α diffraction (b2) and those giving quasi-ω diffraction (b3) produced by the inverse FFT using the Bragg reflections. (c) Projected atom columns from the corresponding constructed structures, including perfect β (c1), two-layer modulated (c2) and three-layer modulated (c3) structures, and (d) intensity profiles of the outlined (in red) atom columns in (b), including perfect β (d1), two-layer modulated (d2) and three-layer modulated (d3) structures.
