Dwell fatigue in two Ti alloys: An integrated crystal plasticity and discrete dislocation study

- The thermal activation energies for both Ti alloys are determined.
- The markedly different cold creep responses of Ti-624x alloys are captured.
- Nano-indentation analysis of crystallographic orientation-dependent rate sensitivity.
- The first explained why alloy Ti-6242 shows a dwell debit but Ti-6246 does not.
