- •
Cr2O3 scale having tens nanometer sized grains was formed on Sanicro 25 at 650 °C.
- •
M23C6 carbides was thermodynamically unstable in Cr-depleted zone. Beneath the Cr2O3 a layer with short-range ordering typical for glass was formed.
- •
Nanometer sized Cu-rich particles were precipitated from the austenitic matrix.
