Abstract

A method is presented to predict the oxidative life of intermetallics. The method is demonstrated by predicting the lifetimes of several aluminides undergoing cyclic oxidation at 1200°C. For NiAl and NiAI-Zr alloys, the lifetimes were predicted at several other temperatures as well. Using a critical surface recession failure criterion, it is shown that several aluminides (e.g., NiAl and FeAl) have long-term oxidation resistance (∼ 10,000 hours) to approximately 1150°C. Aluminides containing reactive elements (e.g., NiAI-Zr alloys) have long-term oxidation resistance to approximately 1 200°C. The method is also applied to predict the oxidative lifetime of MoSi2 at temperatures of 1200°-1400°C which shows that the oxidation resistance of MoSi2 is significantly better than that for the aluminides. For the same failure criterion, it is shown that MoSi2 can exhibit long-term oxidation resistance (∼ 10,000 hours) at temperatures in excess of 1400°C. Use of the method to predict the maximum use temperature is also demonstrated for NiAl and NiAI-Zr alloys.
