This paper presents a method to optimize crystal orientation of Nickel-based single crystal turbine blade. Total strain range, crystal orientation and temperature range have effect on the low cyclic fatigue life of Nickel-based single crystal superalloy, on other invariable thermo-mechanical cycle conditions. The experiment data of many concerned literatures were analysed and how crystal orientation effect single crystal blade damage and fatigue life was derived The evaluating method for fatigue life of single crystal superalloy was proposed The 3 dimensional Nickel-based single crystal turbine blade was modeled in MARC program and this finite element model was capable of accounting for...
