Synergistic effect of Y and Nb on the high temperature oxidation resistance of high Nb containing TiAl alloys

The synergistic effect of Y and Nb addition on the long time isothermal and cyclic oxidation behaviors of Ti–45Al–(6–9)Nb alloys containing 0.1–0.4 at.% Y was investigated in air at 900 °C. The results showed that the high temperature oxidation resistance was improved with an increase of Nb content....
