Abstract

The effects of maximum stress on crack initiation and propagation, the fracture life, and the dynamic creep rate have been studied on the basis of a fatigue-creep interaction fracture map. A number of maximum stress modified equations have been deduced to describe the complete interaction behavior of a large ESR-Cast-to-Shape superalloy disk under a wide range of fatigue and creep stress combinations at a constant temperature. All the observed fracture lives fall within a range of a factor of two of fracture lives predicted by these equations.
