Abstract

The phase constitution and associated oxidation behavior were determined for an alloy of composition (in wt%) Ni-31.5Cr-11.5Al-0.61Y. The identity, relative amount, and approximate composition of each phase were determined after equilibration at 700, 900, and 1100°C using SEM/EDS, XRD, and image analysis. The CALPHAD method was used to predict the phase equilibria in this system, and the results showed good agreement with experiment. Cyclic oxidation behavior at 900, 1050, and 1100°C in air was determined and assessment of the results was aided by CALPHAD predictions in conjunction with dilatometric measurements.
