Fatigue design with cast magnesium alloys under constant and variable amplitude loading

For a fatigue design of cast components of magnesium alloys AZ 91 HP, AM 50 HP and AM 20 HP strain and stress controlled fatigue data, influence of notches, main stresses, elevated temperatures and at last but not least the knowledge of cumulative fatigue behaviour is needed. This data is compiled in the presented paper and compared with cast aluminium alloys. The principles of component design are discussed.
