Cyclic creep and stress rupture results of Inconel MA 6000E are reported and discussed as a function of frequency, Inconel MA 6000E, a new alloy system developed for high creep resistance at intermediate as well as at high temperatures, is a mechanically alloyed oxide dispersion (about 2.5 vol pct) and ..gamma.. precipitation (about 50 vol pct) strengthened superalloy. A decrease in the minimum strain rate and increase in the rupture life accompany cyclic frequency increase. Deceleration of the creep rate is related to anelastic strains recovered during off-load periods. The data are also discussed relative to an alloy containing only the oxide dispersoids.
