A microstructural study of the oxide scale formation on ODS Fe–13Cr steel

High-temperature oxidation resistance of ultrafine-grained 14 %Cr ODS ferritic steel

“…1b). Hence, it emphasises that the ODS RAF steel exhibits outstanding oxidation resistance, similar to the results reported by Hoelzer et al [12] for the Fe-13Cr ODS ferritic steel.…”

Effect of Chromium Content on the Oxidation Behaviour of Ferritic Steels for Applications in Steam Atmospheres at High Temperatures

“…9 and shows the phases in equilibrium when the steam fraction is lower than 1 vol.%. The Cr 2 O 3 is the only stable phase when the steam fraction can be considered as a impurity, which is in agreement with other authors, which explain that the Cr 2 O 3 phase is mainly formed on the surface of the 9-12% Cr ferritic-martensitic steels in dry air atmospheres at temperatures higher than 600°C [3,4], although in atmospheres composed by mixtures of water vapour and air the scales are formed of other less protective oxides than Cr 2 O 3 , such as Fe 3 O 4 and (Fe,Cr) 3 O 4 [1,5,6]; finally, other authors have reported that on Fe-13% Cr steel with dispersed yttria, at 700°C, the scale in contact with the gas is mainly composed of (Fe,Cr) 3 O 4 and at the temperature of 800°C is composed of Cr 2 O 3 [22].…”

“…This can be favoured by an appropriate control of the microstructure, the chromium supply to the surface is raised by introducing an increased number of fast diffusion paths into the alloy, such as dislocations or grain boundaries [12,22].…”

Effect of Ti and W on the Mechanical Properties and Microstructure of 12% Cr Base Mechanical-alloyed Nano-sized ODS Ferritic Alloys

“…It has been reported by a number of researchers [1][2][3][4][5][6][7][8][9] that MA ODS alloys possess excellent creep strength at high temperatures and high resistance to swelling in radioactive radiation. Oxide dispersion strengthened (ODS) ferritic alloys produced by mechanical alloying (MA) have been found to be effective for increasing high-temperature strength.…”
