Abstract

In the present paper, the effect of the contents of Nb, Mo, V on the oxidation properties (700°C, in air) of Ti3Al based alloys has been studied. It has been shown that the alloys were oxidized rapidly as exposed at 700°C in the air. After 100 h exposure, oxygen-affected alloy surface layer of about 10 μ thickness has been formed on account of the poor protection of the oxide film. An addition of (11–13%)1 Nb enhanced the oxidation resistance. The addition of Mo and V in the Ti3Al−Nb system alloy reduced the oxidation resistance significantly.
