“…Studies on the low-frequency damping capacities of as-extruded Mg-11.2Li-0.95Al-0.43Zn alloy revealed that the high-temperature damping background for the alloy exhibits a viscoelastic relaxation characteristic. This alloy possesses extremely low activation energy for a high-temperature damping background due to its abundant ␣/␤ phase boundaries [9]. In addition, the Mg matrix composite has been developed to obtain higher damping capacities than the commercial magnesium alloys.…”

“…The damping performance of the alloys improves when the crack opens and decreases when the crack expands. Wu et al [36] found a P3 damping peak in extruded Mg-11.2Li-0.95Al-0.43Zn at 215 °C and low frequency. The XRD experiments showed that the appearance of the P3 peak is related to recrystallization process and grain growth, but the specific mechanism needs further study.…”

Magnesium alloys with high damping, high specific strength and low density have attracted great attention in recent years. However, the application of magnesium alloys is limited by the balance between their mechanical and damping properties. The strength and plasticity of magnesium alloys with high damping performance often cannot meet the industrial requirements. Understanding the damping mechanism of magnesium alloys is significant for developing new materials with high damping and mechanical properties. In this paper, the damping mechanisms and internal factors of the damping properties of magnesium alloys are comprehensively reviewed. Some damping mechanisms have been studied by many scholars, and it has been found that they can be used to explain damping performance. Among existing damping mechanisms, the G-L dislocation theory, twin damping mechanism and interface damping mechanism are considered common. In addition, some specific long-period stacking ordered (LPSO) phases’ crystal structures are conducive to dislocation movement, which is good for improving damping performance. Usually, the damping properties of magnesium alloys are affected by some internal factors directly, such as dislocation density, solute atoms, grain texture and boundaries, etc. These internal factors affect damping performance by influencing the dissipation of energy within the crystal. Scholars are working to find novel damping mechanisms and suitable solute atoms that can improve damping performance. It is important to understand the main damping mechanisms and the internal factors for guiding the development of novel high-damping magnesium alloys.

The effects of aging treatment on the damping capacities of ZA84-xSb alloys were studied. The results show that in the aging treatment process, because of following mainly reasons: (1) the dissolution of the ternary phases, (2) the increase of grain interfaces, (3) the increases of dislocation density, and (4) the micro deformations of matrix interfaces and the second phases, the damping capacity of ZA84-xSb magnesium alloys did not be reduced. On the contrary, whether at the low temperatures or high temperatures, its damping capacity is higher than as-cast alloy, which is of great significance for the application of ZA84-xSb magnesium alloys.
