Abstract Scope The Ti6Al4V alloy is extensively used in aerospace, automotive or biomaterial applications. In the aerospace industry, the service temperature of Ti6Al4V is currently limited to 350 °C due to its insufficient oxidation resistance. Oxidation causes the formation of an unprotective oxide scale and an oxygen enriched subsurface layer, which is known as “alpha-case”. Additionally, the effect of water vapor on oxidation resistance is critical. In the present study, the oxidation behavior of Ti6Al4V in dry air and air containing 10 vol. % H2O at 500, 600 and 700 °C for up to 500 hours has been investigated. The main focus of this study is the examination of oxide scale morphologies and oxygen enrichment in the subsurface zone. From the oxygen concentration profiles the alpha-case thickness as a function of temperature and time is determined. In addition, the influence of nitration and the beta-stabilizing element vanadium is discussed.
