Effects of temperature (760 degrees C and 980 degrees C), crystallographic orientation ([0 0 1], [0 1 1] and [1 1 1]) and dwell types (tensile, compressive and balanced dwell type) on low cycle fatigue (LCF) of a Ni-based single crystal (SC) superalloy are experimentally investigated and modeled. Since the LCF behavior shows strong crystallographic orientation and dwell type dependences, corresponding accurate life models are needed for safe application in gas turbine components. The feasibility of stress-based, strain-based and energy based models on anisotropic fatigue behavior was evaluated. A modified Cyclic damage accumulation (CDA) method combined with critical slip plane concept is developed to correlate the influence of orientation and dwell type on LCF data. (C) 2012 Elsevier Ltd.
