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 kinetics, morphology and composition were studied by thermogravimetry in combination with SEM/E...
