Abstract: Atom probe tomography, electron probe microanalysis and nanoindentation was used to characterise the oxygen-rich layer on an in-service aerospace engine compressor disc, manufactured from the titanium alloy TIMETAL 834. Oxygen ingress was quantified and related to changes in mechanical properties through nanoindentation studies. Contributions of crystallography and microstructure to hardness changes are qualitatively discussed. The role of microstructure on oxygen ingress was studied and oxygen ingress along a potential α / β interface was directly observed on the nanoscale using atom probe tomography.
