Abstract
TiAl intermetallics are one of the most promising
structural alloys used at high temperature. However, the
poor oxidation resistance at temperature above 750°C has
°
hindered their practical engineering applications. In this
γ paper, we review the oxidation behavior, kinetics and mechanism of TiAl alloys. The reported feasible surface
modification methods to improve the high temperature oxidation resistance of TiAl alloys are also reviewed.
