Data for: Quantification of the effect of oxygen on mechanical properties of TIMETAL 834

Data is in the Excel file format. Data enables reproduction of the figures in the publication "Quantification of the effect of oxygen on mechanical properties of TIMETAL 834". 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.

摘要：本研究采用原子探针层析成像（Atom Probe Tomography）、电子探针显微分析（Electron Probe Microanalysis）及纳米压痕（nanoindentation）技术，对由钛合金TIMETAL 834制备的服役态航空发动机压气机盘表面的富氧层进行表征。通过纳米压痕实验对氧元素渗入行为进行量化分析，并将其与力学性能变化建立关联。定性探讨了晶体学与微观组织对硬度变化的作用机制。研究了微观组织对氧元素渗入的调控作用，并通过原子探针层析成像在纳米尺度下直接观测到潜在α/β界面处的氧渗入行为。
