| Abstract: | Based on the mesco-and micro-structure change and damage characteristic of the Ni-base singlecrystal superalloy,an united-two parameters creep-damage constitutive equation and the life predictive model havebeen set up in this paper.Primarily tested by experiments,the models can predict,in considerable condition,thesteady and teritary creep and rupture condition. |
