High Temperature Oxidation Behaviour of TiAl-Based Intermetallics

Ti-Al based intermetallic compounds have attracted considerable interest as structural materials for high-temperature applications due to their low density and substantial mechanical strenght at high temperatures. However, one major drawback hindering industrial application arises from theinsufficient oxidation resistance at temperatures beyond 700 C. In the present contribution some generalaspects of high temperature oxidation of Ti-Al-based intermetallics will be presented. This will be followed by a discussion of the influence of alloying elements, in particular niobium, and of the effect of nitrogen in the oxidizing environment on the high temperature oxidation behaviour of such materials.
