Abstract

It is demonstrated that phase sensitive synchrotron microtomography in the Fresnel wave propagation regime can be used to 'non-invasively and directly see in real time' the interaction between microstructure and damage mechanisms in multiphase Ti alloys. Using a combination of absorption and phase contrast imaging during in situ fatigue experiments on the ID19 micro-tomography beamline (at ESRF France), we have captured in real time some of the important microstructural damage processes occurring in two different classes of titanium alloys: Ti-6246 (Ti-6Al-2Sn-4Zr-6Mo, an α+β titanium alloy) and BurTi (Ti-2.5V-15Cr-2Al-0.2C, burn resistant β-titanium with reinforced titanium carbides). It is envisioned that this capability will prove to be a boon for further understanding the behaviour and optimization of microstructures in multiphase structural alloys.
