| Abstract: | The predict methods about creep break life of the structure in high temperature are studied. The creep constants of the single crystal named DD3 are obtained on the basis of creep tests. The L M method, θ method and improved θ method are used to predict the creep life of the single crystal turbine blade being used in one engine of a plane. All the results obtained are valuable to engineering applications. |
