Fatigue Life Prediction of Al319-T7 Subjected to Thermo-Mechanical Loading Conditions

This study investigated a fatigue life prediction method based on extensive experiment results of cast aluminum alloy Al319-T7 subjected to repeated thermal and mechanical loading. Cyclic tests and fully reversed fatigue test results of the material were obtained from the specimens subjected to three different strain rates (5x10-5, 5x10-4 and 5x10-3) and various temperature conditions. At each strain rate the specimens were subjected to room...
