Effect of water vapor on high-temperature oxidation of FeCr alloys
The suppression of protective chromia scale formation in water vapor containing service environments limits in many cases the upper application temperature of high-Cr martensitic and ferritic steels. The prese...

Effect of oxygen partial pressure on the oxidation behaviour of an yttria dispersion strengthened NiCr-base alloy
An yttria dispersion strengthened NiCr-base alloy was studied with respect to isothermal oxidation behaviour at 1000 °C and 1050 °C in high- and low-pO2 gases, i.e. Ar–O2 and Ar(−H2)–H2O. The scale growth kinetic...
