Short- and long-term oxidation behaviour of an advanced Ti2AlNb alloy

Abstract : The oxidation behaviour of an advanced Ti2AlNb alloy was investigated over a temperature range of 650–800 °C in lab air for short- and long-term experiments. The mass gain increased with time and temperature and oxidation kinetics was parabolic at 650 and 700 °C for durations up to 1000 h, while the parabolic oxidation rate was changed at 800 °C between 500 and 1000 h. Long-term oxidation experiments revealed oxide scales composed of alternating TiO2 and AlNbO4 layers. Results showed an improvement of the oxidation behaviour of the present alloy as compared to other titanium base alloys, including Ti2AlNb alloys.
