FIM ATOM PROBE INVESTIGATION OF LONG PERIOD SUPERSTRUCTURES IN Cu3 ± xPd

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.
