“…The solute atoms will deform the crystal lattice, change the lattice parameters, and form clusters with surrounding atoms. Because of the diversity of electronegativity, a variety of atomic clusters will be produced [ 9 ]. Based on the EDS results in Table 2 , the particles could be inferred as α-Mn particles or Y-rich particles.…”

“…It is not necessary to add damping components and only consume energy through itself [ 7 ]. Studies have shown that high-purity magnesium has very good damping performance [ 8 , 9 ], which is much higher than other metal materials. However, the addition of most alloying elements will reduce its damping characteristics [ 10 , 11 , 12 ].…”

Magnesium alloys are concerned for its mechanical properties and high damping performance. The influence of Mn toward the internal organization morphology of long-period stacking ordered (LPSO) second phase and the consistent damping performance in Mg-4.9Zn-8.9Y-xMn have been studies in this work. It has shown that the addition of Mn tends to diffuse to the LPSO interface and causes the LPSO phase to expand in the arc direction. The circular structure of LPSO can optimize the damping property of the alloy better than the structure with strong orientation, especially at the strain of 10−3 and 250 °C. With more additions of Mn, damping would have a reduction due to the dispersed fine LPSO phases and α-Mn particles. When the Mn content is higher than 1.02%, the grain is refined, and mechanical properties have been significantly improved. Mg-4.9%Zn-8.9%Y-1.33%Mn shows the best mechanical property.

“…Generally, current damping research in Mg alloys is predominantly rationalized under the dislocation damping theory established by Granato and Lücke [17,18]. According to dislocation damping theory, the damping capacity of a material, including Mg alloys, usually increases with increasing strain amplitude within a specific amplitude range [19][20][21]. Thus, a curve of damping versus strain amplitude can be obtained.…”

In this paper, the damping capacities and damping mechanisms of high damping, graphite-reinforced Mg97Zn1Y2 composites were investigated. Composites consisting of different graphite particle sizes (24, 11, and 3 μm) were designed and prepared using the casting method. The microstructure of the composites was examined using optical microscopy (OM) and transmission electron microscopy (TEM), which confirmed that the graphite particles were successfully planted into the Mg97Zn1Y2 matrix. Measurements made with a dynamic mechanical analyzer (DMA) showed that the Grp/Mg97Zn1Y2 composite has a high damping capacity. At the anelastic strain amplitude stage, the damping properties of the Grp/Mg97Zn1Y2 composites were found to be higher than those of the Mg97Zn1Y2 alloy. Furthermore, decreasing the graphite particle size was found to improve the damping properties of the Grp/Mg97Zn1Y2 composites. At the microplastic strain amplitude stage, the damping properties of the Mg97Zn1Y2 alloy were found to be higher than those of the Grp/Mg97Zn1Y2 composites. Moreover, the damping properties of the Grp/Mg97Zn1Y2 composites were found to decrease with increasing graphite particle size. The reason for the increased damping of the Grp/Mg97Zn1Y2 composites during the anelastic strain amplitude stage can be attributed to the increase in the number of damping sources and weak interactions among the dislocation damping mechanisms. At the microplastic strain amplitude stage, the damping properties of the composite are mainly affected by the activation volume of the slipped dislocation.

“…Luo et al [9] conducted damping loss factor testing and sound transmission experiments on AZ31B magnesium alloy with micro-arc oxidation coating and electrophoretic deposition process, an improvement in the frequency range of the damping loss factor from 0−850 Hz was observed and improvement in bending stress improves losses in sound transmission. Parande et al [10] [11] investigated alloying elements influence in a solid solution of binary magnesium alloys through damping and mechanical properties investigation. The alloys yield strength and independent strain-amplitude related damping are mainly associated with the lattice distortion.…”

For a varsity of application, materials are demanded with high damping that can lower fundamental natural frequencies, and composites offer widespread options towards designing space structure with lightweight which are controlled effectively. Damping fixtures were made with lightweight composites, for the purpose of transporting aerospace components from one place to another. This present work investigates the damping characteristics of lightweight magnesium-based composite (AZ31+x%Si3N4), subjected to vibration. The composite cantilever beam is excited using an impact hammer and the vibrations generated are recorded using a data acquisition system. The damping properties are related to the density and microstructure of the fabricated composites. Results show that the damping factor changes with higher reinforcement of Si3N4 ceramic particulates and the microstructure obtained during casting have an influence on the damping performance.
