The fracture behavior transitions in cold dwell fatigue of Ti-6Al-4V

The fracture behavior transitions in cold dwell fatigue of Ti-6Al-4V

Ti-6Al-4V forged materials which had fine grain size and commercial billet which had moderate grain size and micro texture were prepared. Cold dwell fatigue tests were conducted using both materials, and dwell time condition was up to 1800s. Fracture cycles and elongation were almost same on each sp...
