Abstract : FIM atom-probe techniques have been used in order to investigate concentration modulations related to 001 APB-s in Cu3 ± x Pd. Layer by layer analysis of 001 superstructure planes of a long-period single crystal 20.5 % Pd exhibits LRO modulations with correlation lengths oscillating between 6 and 7 d001. The average wavelength 6.5 d001 is in good agreement with the mean size of one-dimensional ordered domains, as measured by HRTEM.
