title = "Effect of non-metallic ceramic inclusions on strain localization during low cycle fatigue of a polycrystalline superalloy",
abstract = "The presence of inclusions in powder metallurgical processed disk materials often leads to competing failure modes and a wide variability in fatigue durability in low cycle fatigue. For robust models for fatigue and prediction of the variability in this property, the impact of such inclusions on the fatigue crack initiation process has been studied. Fatigue experiments in the low cycle fatigue regime on an intentionally seeded Ren{\'e} 88DT polycrystalline nickel-base superalloy were performed at 400 °C and 650 °C to evaluate the effect of non-metallic ceramic inclusions on the strain distribution and fatigue initiation process. Advanced high resolution digital image correlation measurements were performed to related strain fields at the grain scale to microstructure surrounding non-metallic inclusions.",
