Abstract: The effect of nanocrystallization on oxidation resistance of TiAl intermetallics at 800～900 ℃ was investigated. Both of cast TiAl and nanocrystalline TiAl formed TiO 2+Al 2O 3 complex scales. Their isothermal oxidation kinetics all followed the parabolic rate law. The nanocrystallization of TiAl improved the cyclic oxidation resistance of TiAl significantly due to the enhancement of scale adhesion.
