). The damping ability(tanδ) of the alloy was characterized by dynamical mechanical analyzer(DMA). It is found that the damping ability(tanδ) retains a very high level which is all above 0.05 from...Microstructure and damping properties of MnCuNiFeCe alloyFeng-Shuang Lu1,2,3,Bin Wu1,3,Jian-Fu Zhang1,3,Ping Li2,Dong-Liang Zhao1,31.

INFLUENCE OF HEAT TREATMENT ON DAMPING BEHAVIOUR OF THE MAGNESIUM WROUGHT ALLOY AZ61 K.U. Kainer1,K. Steinhoff2,D.Letzig1,J.Timmerberg3,R. González-Martínez1,J. G4 (1.Institute for Materials... for 1h on variation of damping, hardness and microstructural change of the magnesium wrought alloy AZ61 was investigated. Damping and hardness behaviour could be attributed to the evolution......

application. The EPD film changes the damping characteristic of magnesium alloy, and both the MAO and EPD process change the bending stiffness of samples being treated. Damping loss factor (DLF) test and sound... for the surface treatment to enhance the damping loss factor, LST and widespread application of magnesium alloy while improving the corrosion resistance.Key words:magnesium alloy; micro arc oxidation......
that the damping capacity of the MMCs is proportional to the volume fraction of graphite and the addition of SiC in aluminum alloy has no evidence to improve in damping capacity. However, the MMCs made by gravity... damping mechanisms in the particle reinforced MMCs were discussed.2 Experimental The matrix alloy in the paper was 2024Al with chemical composition (in mass fraction) 4.79%Cu, 1.49%Mg, 0.611%Mn, 0.245......
of temperature and vibration frequency[3]. As a kind of high damping alloy, Zn-Al alloys have been investigated first by Nowick[4], who studied the relationship of the precipitated phase and the internal...). The investigation indicates the possibility of simulating the damping behavior of Zn-Al alloy with fully lamellar microstructure by numerical method. Also in applications it is more valuable......

vibrational damping capacities[5,7]. But almost no paper reports the damping properties of the aluminum alloy-FA composites. As an important parameter of structural materials, the damping properties... intrinsic damping of the FA. Unlike the usual SiC or C continuous fiber reinforced aluminum alloy composites[14], the dislocation density in the as-cast and age-hardening 5% (mass fraction) FA/Al composites......
