Abbreviated Series Title Atom-probe field-ion microscopy (APFIM) was employed to study the phase separation process in a Cu-33.3at%Ni-1.7at%Cr ternary alloy. Formation of the coherent second phase was clearly observed after aging for 15 min at 823 K. Although no discrete precipitates were recognized in the Ne-ion image before 15 min aging, APFIM results showed a broadening in the concentration fluctuations. A grand-canonical (Gaussian) distribution was used to described the time evolution of the frequency distribution of Ni in the composition profiles. From the logarithmic plot of the relative change in variance versus aging time, the relaxation time for the clustering of Ni was determined.
