Cyclic Deformation Behavior of the Cast Magnesium Alloy AZ91

Endurance limit of die-cast magnesium alloys AM50hp and AZ91hp depending on type and size of internal cavities

“…They verified that crack propagation occurs mainly by the coalescence of smaller cracks. Höppel et al carried out fatigue experiments at AZ91 and point out that for crack initiation cavities at or beneath the surface play an important role [8]. Badini et al establish a connection between mechanical properties and cast defects in Al and Mg die-cast alloys [9].…”
