Abstract

NiAl and NiAl/TiB2 composites were tested in air at 800, 1000, and 1200°C. The oxidation resistance of the composites depends on the fabrication route, and subsequently on the reinforcement phase morphology and distribution. The oxidation resistance of NiAl reinforced with large TiB2 particles was found to decrease with increasing TiB2 content. NiAl reinforced with large TiB2 particles was completely oxidized at 1200°C after a 100 hour exposure.
