Abstract

Recently, a two phase TiAl/Ti3Al bulk microcrystalline system between room temperature (RT) and 1000°C applying in situ XPS analysis on its low-pressure oxidation characteristics was reported. The key finding was that at high temperature a new ternary oxide phase-Al2TiO5-appears changing the composition of the surface substantially. This paper shows that the formation of Al2TiO5 increases the oxidation resistance.
