Abstract
Based on the tensile stress-dominated low cycle fatigue (LCF) tests at 760°C, the fracture morphology of a second-generation Ni-based single crystal superalloy (SC) was studied in this paper. It was found that under LCF loading the specimen cracked with one fatigue source. The angle of fatigue bands in crack propagation region was related to the secondary orientation deviation from crystal orientation [100]. In addition, evidence showed that the...
