Abstract

This study investigated the vibration fracture behavior of two Mg-Zn-Al alloys, AZ31 and AZ61 in as-extruded and as-annealed states. The effects of deformation twins, precipitates and Al concentration on vibration properties were examined. As-extruded AZ31 specimens showed a longer vibration life than the others, mainly because of better damping capacity and a lack of intergranular Mg₁₇Al₁₂ precipitates.
