Abstract
Using atom probe tomography, the three-dimensional morphology and composition of nanoscale omega precipitates in a simple binary titanium–molybdenum alloy have been uniquely determined. The results include the average composition of the omega precipitates and the partitioning of Mo across the ω/β interfaces. These investigations also revealed compositional inhomogeneity within the nanoscale precipitates, with the presence of a Mo-rich core, presumably arising from the relatively slow rate of Mo rejection during isothermal growth of these omega precipitates.
