The rupture life prediction in cold dwell fatigue of Ti-6Al-4V based on the creep deformation [PDF]
MATEC Web of Conferences, 2020 Titanium a lloys have been found that the fatigue strength of Ti alloys decreases due to cold dwell fatigue (CDF) at room temperature. Ti and Ti alloys generate creep deformation at room temperature (T/Tm = 0.15).
