TL;DRAbstract

minimum at approximately 10 ppm. The creep rate is CO/sub 2/ at equivalent stress and temperature was lower by a factor of 3 than the minimum rate observed in oxygen. Chemical analyses, metallography, and experiments with carbon showed that carburization occurred in pure flowing CO/sub 2/ in the temperature range studied. From this evidence it was concluded that the strengthening observed in CO/sub 2/ was primarily due to carburization. The creep- and tensile-fracture strains were adversely affected by exposure to CO/sub 2/, with the magnitude of the effect dependent on the time and temperature of exposure. (auth)
