Creep life is mainly determined by the growth of voids until a critical stage is reached when final failure takes place. Based on metallurgical considerations, there are many models for the growth of voids in creep. However, in many operating conditions the components are subjected to both hot corrosion and creep, which accelerate the failure process. In the present analysis a model is proposed for life prediction under the interacting conditions of creep and hot corrosion based on the fracture mechanics parameter, the energy rate line integral C*. This model appears to describe experimental data on Type 304 stainless steel well.
