- •
Competitive surface segregation of Si, Nb and Ti occurs above 550 °C.
- •
Surface segregation is favored to the 〈111〉 oriented grains.
- •
Surface segregation of Cr is limited at the Ti/Nb precipitate locations.
- •
The optimization of microstructure facilitates the fast growth of protective scale.
