Part III: Oxidation behaviour of optimised MoSi 2 composites The topic “Oxidation behaviour of particle reinforced MoSi 2 composites at temperatures up to 1700°C” is discussed in a three part publication. In the first part of this paper a literature survey on the oxidation behaviour of MoSi 2 and MoSi 2 composites has been given. In the second part an initial screening at 1600°C revealed those composites which may be suitable for high temperature applications. The low temperature oxidation behaviour of selected composites in the “pest” region was examined as well. Additionally, the effect of iron impurities on the high temperature behaviour of the composites was explained. The present part deals with a detailed investigation of an optimised MoSi 2 /HfO 2 composite. These investigations include high temperature oxidation at 1500 to 1700°C and low temperature oxidation at 400 and 500°C.
