The oxidation behavior of Ni-6wt.% Cr alloys with various concentration of alumina dispersions(5vol.% 10vol.%) was determined at 1000 and 110$0^{circ}C$ in oxygen of 1 atm. pressure. Some general observations were ascertained. These include: (a) the addition of alumina dispersoids significantly increased the oxidation resistance of Ni-6wt.% Cr alloy; (b) the rate of oxidation was distinctly decreased as a function of the volume percent of oxide dispersion; and (c) the presence of alumina dispersions promoted the formation of continous, protective Cr2O3 layer at 6 wt.% Cr.
