Abstract Scope |
A correlative approach to microstructural mapping is presented, directly correlating mechanical properties data from nanoindentation with crystallographic data from Electron Backscattered Diffraction (EBSD) and compositional data from Electron Probe Microanalysis (EPMA). This is complemented by nanoscale compositional analysis through atom probe tomography (APT). Variations in mechanical response as a function of crystal orientation, composition and spatial position are measured using thousands of data points, rather than obtaining representative properties from smaller sample volumes. The approach is applied to a model titanium alloy and is also used to quantify the effect of oxygen ingress on the mechanical properties of an ex-service jet engine component. These case studies demonstrate the ability of the approach to rapidly obtain high-resolution data on structure-property relations from multi-component, industrially relevant systems. |
