Abstract

High and low cycle fatigue tests were conducted for extruded magnesium alloys, AZ31 and AZ61. In the high cycle fatigue properties, AZ61 showed higher fatigue strength than AZ31, while both alloys did not show fatigue limits. In this case, the rotating bending tests revealed higher fatigue strength than uniaxial loading tests. In the low cycle fatigue properties, AZ31 and AZ61 revealed almost equal fatigue strength under constant strain amplitude tests. However, the hysteresis loops were very unique, showing anisotropy between tension and compression sides.
