Phase separation of g 0 precipitates determines the microstructure and mechanical properties of nickel-based superalloys. In the course of ageing, disordered g spheres form inside ordered (L1 2 ) g 0 precipitates, undergo a morphological change to plates and finally split the g 0 precipitates. The presence of g particles inside g 0 affects coarsening kinetics and increases alloy hardness. Here we use atom probe tomography to visualize phase separation in a Ni 86.1 Al 8.5 Ti 5.4 alloy in three dimensions and to quantify the composition of all the phases with near-atomic resolution. We find that g 0 precipitates are supersaturated in nickel, thereby driving the formation of g particles and observe a compositional evolution of the g particles, which accompanies their morphological change. Our results suggest that by controlling nickel supersaturation we can tailor the phase separation and thereby the properties of nickel-based superalloys.

Thin Films / Battery Electrodes / Microscopical Analysis / Glass Membranes / Ionic ConductivityThin film ion-conductive materials may represent essential components of future all-solidstate batteries. Besides, they are also of interest from a fundamental point of view. In this article, the deposition of thin films of complex oxides and amorphous glasses is discussed. Methods of local chemical analysis by analytical electron microscopy and atom probe tomography are described and studies of atomic transport in sputtered network glasses are presented. As experimental examples, thin films of Li borate and silicate glasses, LiCoO 2 , V 2 O 5 , and Li 4 Ti 5 O 12 are addressed.
