Abstract

Abstract

The oxidation kinetics of N18 alloy at the temperatures of 600℃～1200℃ in steam were investigated.The results showed that the oxidation kinetics was changed by varying the oxidation temperatures due to the phase transformations of the base metal and its oxide;parabolic rate（600℃～700℃） → parabolic-linear rate（800℃） →cubic rate（950℃） →cubic（or parabolic） linear rate（1050℃） →parabolic rate（1100℃～-1200 ℃）parabolic rate（at 1100℃～1200℃）.And the oxidation resistance of the N18 alloy at all the temperatures was superior to that of Zircaloy-4 from the higher rate exponent due to the Nb addition.
