Abstract
The fatigue behavior of the high-pressure die cast magnesium alloys AM50 and AZ91 was investigated. In both alloys, cast defects led to marked scatter in fatigue
performance.
To study potential improvements in fatigue behavior, shot peening was performed using various Almen intensities. Both alloys showed marked improvements in fatigue strength
compared to an electropolished reference.
