Oxidation and Hot Corrosion of Ni-Cr-and Co-Cr-Base Alloys Containing Rare Earth Oxide Dispersions.

摘要

The objectives of the program were to determine the effects of rare earth oxide dispersions on the oxidation and hot corrosion of Ni-Cr-and Co-Cr-base alloys,with emphasis on alumina scale-forming Co-base alloys. The results generated are intended to provide a better understanding of the compositional requirements of oxidation-resistant and hot corrosion-resistant superalloys for high-temperature service in severe environments.
