We have succeeded in direct observation of the atomic arrangement in athermal and isothermal ω-phases in Zr-7.5 at.% Nb alloy by high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM), although the atomic displacement along 〈0 0 0 1〉 has not been determined quantitatively. The orientation relationship between ω- and β-phases is visualized on atomic scale.
