  • DARWIN Roadmap for Cold Dwell Fatigue
    DARWIN® Roadmap for Cold Dwell Fatigue
    Sobotka, James C ;
    Enright, Michael P
    2024-06-01 | PDF
    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 ...
