The crack propagation model successfully applies to life‐prediction of near‐α‐titanium alloy IMI 834 under complex high‐temperature fatigue‐loading conditions. The predictive capabilities of the model can be attributed to the close correlation of the model with the relevant damage mechanisms (among them environmental degradation under varying conditions) and micro‐structural processes. The Figure shows an SEM image of a typical crack‐initiation site for a test run at 400 °C.
