Abstract
The fact that the α/β titanium alloy Ti-6Al-4V is sensitive to cold dwell loading regimes has recently been endorsed by a combination of evidence gathered from fatigue studies performed on laboratory scale specimens and the findings of a failure investigation into an in-service fan disc failure.

The fact that the α/β titanium alloy Ti-6Al-4V is sensitive to cold dwell loading regimes has recently been endorsed by a combination of evidence gathered from fatigue studies performed on laboratory scale specimens and the findings of a failure investigation into an in-service fan disc failure. This work confirms that Ti-6Al-4V can demonstrate dwell characteristics under fatigue loading, subject to the microstructure and micro-texture developed during thermo-mechanical processing. Additional fatigue data are presented to support this conclusion, together with detailed metallographic and crystallographic characterisation to identify the factors controlling inhomogeneous strength, stress distribution and the crack initiation process on the micro to macro scale. |
