%, 4.0%) alloys, the damping capacity decreases with the increase of Y content. However, for the ZK60-xY (x=2.5%) alloy, the damping capacity improves abnormally, which is possibly related to the formation of Mg3Y2Zn3 (W) FCC phase in this alloy. Key words: magnesium alloys; microstructure; mechanical property; damping capacity; Granato-Lücke Theory1 Introduction Vibration and noise pollution......

amplitude dependent damping of as-cast hypoeutectic Mg-Ni alloy with different Ni contents In the case of a material containing multiple phases,the overall mechanical properties are intimately coupled... temperature condition. The reduction of the damping value of high Ni contained alloy is due to the volume fraction and dimension reduction of α-Mg dendrites. References [1] AVEDESIAN M M, BAKER H. ASM......

of Ti2AlC/AZ91D composites. DENG et al [24] found that the measuring temperature largely determined the damping capacity of AZ91 alloy and its composites. Generally speaking, the effect of the reinforcement, amplitude, frequency, temperature and alloy composition on the damping capacity of the composites and the corresponding mechanism have always been the key issue of the research. In our previous......

alloys decrease with increasing lithium, while the ductility increases apparently; the damping capacity of Mg-Li-Al alloys increases with the rises in temperature and lithium content. For Mg8Li1Al alloy, the damping capacity can go up to 0.01. The higher damping capacity of Mg-8Li-1Al alloy may contribute to the interface damping between α (Mg) and β (Li) phases. Keyword:
