Abstract

The effects of isothermal oxidation on the creep response and porosity of E-Brite foams at 800°C were investigated. Samples of 43.2% and 51.4% porosity were first oxidized in static laboratory air up to 200 hours to determine oxidation kinetics. Select samples were removed after 10 and 100 hours of oxidation and then creep tested to characterize the impact of scale growth on mechanical response and changes in porosity. Significant creep strengthening was observed even when minimal oxide growth occurred. Although oxide growth led to reduced pore size and choked fenestrations, the reduction in open porosity after 200 hours of exposure remained less than 10%.
