Abstract:

Cold dwell fatigue (CDF) is a time-dependent process in near-alpha titanium alloys at temperatures below 300°C that involves metal degradation in the presence of creep to produce cracking on low-energy fracture facets in preferentially oriented, hard-alpha grains. It can cause significant reductions in fatigue life, and experience has shown that it can potentially result in catastrophic rotor failure. Well established methods have not been developed to incorporate this failure mode into assessments of component life and fracture risk management.
