The effects of dispersions of the oxides Y2O3, ThO2 and Al2O3 on the oxidation and hot corrosion of Ni-20 Cr-base alloys, and of dispersions of Y2O3 on the oxidation and hot corrosion of Co-Cr-base alloys have been studied. Up to 1100C, dispersions of Y2O3, ThO2, and possibly Al2O3 have very similar effects on the oxidation of Ni-20 Cr-base alloys. Author
