“…The strength and the damping capacity of the most metal structural materials (such as Al alloy, Ti alloy, stainless steel, tungsten, etc) are within this range, and the product E s tan d s of these substrates are 0.07 $ 0.4 GPa (Lakes, 2002;Vaidya et al, 1995). Supposing the modulus E c and the damping tan d c of the coating layer are 30 GPa and 0.1 respectively (some high damping metal, such as gray cast iron, InSn alloy and some high-loss viscoelastic materials have such performance, Cook and Lakes, 1995), the results are plotted as tan…”

“…The increase in damping capacity at all temperature ranges should be attributed to the intrinsic damping of heavy metal elements, Pb and Ba. 16 Moreover, an obvious damping peak (denoted by peak I) has been observed in the BaPbO 3 /2024Al composite at a temperature range of 283°C to 315°C.

An aluminum matrix composite containing nanosized Pb particles was fabricated by a powder metallurgy technique based on the 2024Al-BaPbO 3 system. The composite exhibited a high and broad damping peak at the melting temperature range of nanosized Pb particles. The increase in value and breadth of the damping peak was attributed to the dislocation damping of the interfacial matrix close to the nanosized Pb liquid phase. The damping peak is expected to be enhanced by further refining the Pb particle size.

“…Die-cast zinc-aluminum alloys have been shown to have amplitudeindependent damping, which property has been attributed to the predominant thermoelastic damping mechanism [5]. Indium and its alloys possess high damping but considerably insufficient stiffness to support the high loads typically demanded in structural applications [6,[10][11][12][13]. The good damping behavior of these indium alloys has been attributed *Corresponding author: bielt@nus.edu.sg ©KIM and Springer to indium's low-melting temperature (430 K), which translates to high homologous temperature (T H , the ratio of actual temperature to melting temperature) at room temperature.…”

Reduction of the vibration noise from submarine propellers is of interest in naval operations. Such an objective can be achieved via the use of materials with the ability to dissipate energy of vibration by means of heat, i.e. high damping materials. An additional problem is that the extreme hydrostatic pressure environment of a submarine requires the chosen material to exhibit considerably high stiffness. Most materials demonstrate a compromise between the two properties, i.e. stiffness and damping. This paper aims to discuss research into high stiffness and high damping materials conducted using a dynamic mechanical analyzer (DMA) under variations of testing temperature, frequency, and strain amplitude. Alloys of nickel aluminum bronze and indium tin are the subjects of this study. Defect damping represents a large portion of the overall damping properties of the nickel aluminum bronze while increasing indium content is shown to boost the damping properties of the indium tin alloy. The study then continues with the development of a new material that combines both indium alloying and defects introduction into the nickel aluminum bronze alloy. The new alloy is observed to have high damping, as measured in its high tan δ, with minimum reduction of the stiffness |E*|.
