... and oxidation resistance, fabricability and cost. In order to take advantage of the current computational tools for alloy development, a model to account for Ni-Cr alloy oxidation is needed for this temperature range. The oxidation behavior of Ni-based alloys at higher temperature, therefore, should be further...

Paper Number: NACE-2015-6114
.... Based on the successful earlier studies on the development of wrought versions of Alumina Forming Austenitic (AFA) alloys, new alloy compositions have been developed for cast products. These alloys achieve good high-temperature oxidation resistance due to the formation of protective Al 2 O 3 scales...
