Abstract
High-temperature fatigue behavior of cast 319-type aluminum alloys has been studied under loading conditions relevant to operation of high performance engines. The fatigue tests conducted involved both isothermal low-cycle fatigue tests and complex thermomechanical fatigue tests. The tests were used to derive the parameters of a unified constitutive model. The model was verified and its predictive capabilities were demonstrated by comparison with experimentally obtained data. Transmission electron microscopy observations allowed for a correlation of the model parameters with the relevant microstructural processes, and it is demonstrated how such information can be used in modeling of the fatigue behavior. Results on fatigue damage evolution are first presented and their implications for the development of a life prediction model for aluminum castings are addressed.
