Prediction of Creep Rupture Life of Single Crystal Ni-Based Superalloy by Abductive Network

Through establishment of 4 layers Abductive network prediction model between the creep rupture lives of single crystal Ni-based superalloy and alloy composition,creep stress and creep temperature,life prediction of CMSX-4 and CMSX-10 alloys under different experimental conditions were operated,which was verified using the lgtr-lgσ curves obtained by the testing.The results show that the Abductive network could accurately predict the creep rupture life of different single crystal Ni base superalloys.
