ABSTRACT
The relationships between tensile properties and fatigue life in cast aluminum alloys have been reviewed. Strong relationships were found between fatigue life and the quality factor, QT , that uses tensile ductility to characterize structural quality for a number of cast aluminum alloys. The model developed by the authors to estimate the Basquin parameters as a function of QT is introduced along with a step-by-step guide on how to apply it to cast aluminum alloys. This model provides much more reliable estimates for cast aluminum alloys than other models available in the literature.
