Abstract
A cell model with film cooling hole was taken out from nickel-based single crystal cooling blade. Distributions of pressure and temperature in the model were given based on the fluid and heat transfer. An FEM model of crystal was built, and the creep life of cell model was analyzed based on the creep parameters of the different slip systems. The result shows that there is an obvious temperature gradient around film hole. And the distribution of displacement and Von Miese stress has remarkable gradient due to the temperature gradient. The creep life of cell model is influenced greatly by the film hole. And the influence of [111] orientation is much more than [001] orientation.
