【 摘 要 】

As cast magnesium alloys have poor comprehensive properties, such as ductility, hardness, damping properties, etc, which greatly limit the wide application in the industry. In this study, we performed aging treatment on Mg97Zn1Y2 to study the performance changes of the alloy and found that: the particles in the microstructure became finer, and with the aging time increases, the volume fraction of the precipitated phase increases. The mechanical properties of alloys increased significantly. The hardness under aging is 20% higher than that in as-cast, reaching 85.3. The tensile strength increase obviously, reaching 145MPa. The damping property after aging treatment decreases.
