Abstract
The aligned eutectic alloy Ni3Al -Ni3Nb at 1155°C exhibits an initial very rapid rate of oxidation which rate eventually decreases to a very significantly lower level. This decrease in the rate of oxidation has been shown to be associated with the formation of an aluminum oxide layer. The work reported here was conducted to determine both how such a layer forms in oxidation at 1155°C as a function of time and which elements are the active diffusing species in the oxidation process.
