Effect of Ru on Interfacial Re Segregation and Low-Cycle Fatigue Behavior of NiAlRe and NiAlReRu Model Superalloys

The effects of Ru on Re segregation and low-cycle fatigue (LCF) behavior were investigated in two model single-crystal superalloys, Ni-8.5Al-4Re and Ni-8.5Al-4Re-2Ru (wt.%). Microstructural morphology, elemental distribution, fatigue deformation behavior, and dislocation structur...
