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