Key Points
Fatigue crack growth increased significantly in P92 steel exposed to oxygen.
The study observed a 60% increase in crack growth rate when compared to vacuum conditions.
Analysis of fatigue crack growth under varying oxygen levels at 600 °C revealed important insights into material performance.
Enhancing understanding of oxygen's role may help improve the longevity of P92 steel components in industrial applications.
