Abstract

The creep rupture life of Ni-base superalloy was investigated by the BP algorithm based on ANN method.The model of relation among different temperatures

external stress and creep rupture life of the alloy with different compositions was developed.The simulation for creep rupture life of the alloy was conducted through net training.The simulated results was well in agreement with the measured ones.It shows that ANN method is an available and efficient way to predict the Ni-base superalloy’s creep rupture life.
