文摘
- •
Boat-shaped sample was used to study fatigue behavior of Alloy 690 tubes.
- •
Fatigue life of Alloy 690 tubes was longer at 5500 ppb dissolved oxygen than at <5 ppb dissolved oxygen.
- •
Persistent slip bands facilitated rupture of oxide film on Alloy 690 tubes.
- •
High oxide film growth rate at 5500 ppb dissolved oxygen prevents fatigue crack initiation.
