Abstract Based on an advanced neural network method and a huge number of creep rupture life data of nickel base single crystal superalloys, an artificial neural network model is constructed to predict creep rupture life for different types of nickel-base single crystal superalloys. The results indicate that the creep rupture lives can be more accurately predicted with this method for different generations of nickel-base single crystal superalloys. Combined with neural network prediction, the orthogonal analysis method is used to reveal the influence of alloying elements on creep rupture life of the single crystal superalloys with the given composition under 982℃/250 MPa.
