Summary

In this work, fatigue properties of aluminum and zinc containing magnesium alloys are studied in the regime of approximately 106 to 109 cycles to failure. Constant amplitude fatigue properties in ambient air are compared to the performance of the technically widely used age hardened aluminum alloy AlMgSi1. Fatigue data are obtained with the ultrasonic fatigue testing method at loading frequency 20 kHz, which allows measurements in the high and very high cycle regime within reasonable testing times. Fatigue properties as well as the mechanisms of crack initiation will be discussed in wrought, forged, cast and fiber reinforced AZ-magnesium alloys.
