“…Piezoelectric ceramics have been used in high damping MMCs, with the damping mechanism related to piezoelectric effects. Yoshida et al [42] investigated the damping mechanism of metal-piezoelectric ceramic composites. The research indicated that piezoelectric ceramic PbTiO reinforced Cu composite exhibited three to five times higher damping capacity than the pure Cu.…”

“…Quantitative comparison of the damping capacity of materials is difficult, because of the differences in testing method (torsion pendulum methods [5,21,24,27,30,39,42,52,53,67], suspended beam method [4,14,16,18,29], dynamic mechanical thermal analyzer technique [12,15,17,19,22,25,31], Piezoelectric ultrasonic composite oscillator technique), exciting mode (impulse excitation [4,16,18], forced vibration [24,27,30,67], free decay [5,23,39], resonant vibration [30]), testing parameters (temperature, the loading frequency, strain amplitude) [70,71], and specimen configuration (wire, rod, sheet). On the other hand, measures of damping capacity include loss angle (φ), loss tangent (tan φ), inverse quality factor (Q -1 ), loss factor (η), logarithmic decrement (δ) and specific damping capacity (SDC, ψ).…”

Nowadays it is commonly considered that high damping materials which have both the good mechanical properties as structural materials and the high damping capacity for vibration damping are the most direct vibration damping solution. In metals and alloys however, exhibiting simultaneously high damping capacity and good mechanical properties has been noted to be normally incompatible because the microscopic mechanisms responsible for internal friction (namely damping capacity) are dependent upon the parameters that control mechanical strength. To achieve a compromise, one of the most important methods is to develop two-phase composites, in which each phase plays a specific role: damping or mechanical strength. In this review, we have summarized the development of the design concept of high damping composite materials and the investigation of their fabrication and properties, including mechanical and damping properties, and suggested a new design concept of high damping composite materials where the hard ceramic additives exhibit high damping capacity at room temperature owing to the stress-induced reorientation of high density point defects in the ceramic phases and the high damping capacity of the composite comes mainly from the ceramic phases.

“…Also the tensile strength is increased by 42 % when compared with base alloy indicating the possibility of developing high strength and high damping composites. Yoshida et al [31] fabricated PZT reinforced composites and the results confirmed that the damping capacity increases with the addition of PZT reinforcement into Cu matrix.…”

In the present day scenario, materials with high damping capacity and good mechanical properties are significant to suppress mechanical vibrations. In pure metals or alloys, even though the mechanical properties are fairly good, the damping capacity was found to be stumpy. Composites are a better choice which simultaneously exhibits good mechanical properties and high damping values. In the present review, the damping behavior of metals, alloys and its composites is summarized and presented.

In this study, electroceramics PBN and PLZT along with SiC were included in Al-3.96 wt.% Mg (A514.0) master alloy. Ultrasonic cavitation (UST) and mechanical stirring (MS) were employed to improve wettability and dispersion during casting. Two composite systems were produced: PBN system (5 wt.% PBN + 1 wt.% SiC and 15 wt.% PBN + 1 wt.% SiC) and the PLZT system (follows the same designation). The influence of fabrication method on the microstructures, particle distribution and wettability as well as electroceramic impact on dynamo-mechanical properties of prepared composites were investigated. Optical microscope (OM) and scanning electron microscope (SEM) results indicate that the processing technique was effective as it promoted wettability and homogeneous dispersion of particles throughout the Al matrix. Dynamic mechanical analysis (DMA) study of the composites demonstrated that the addition of the functional particles to the Al alloy matrix improved damping capacity (Tan δ) at 200°C. The composites exhibited an increase in Tan δ of 24.3 ± 0.3% and 91.4 ± 0.2% for 5 and 15 wt.% PBN + 1 wt.% SiC and an increase of 19.7 ± 0.5% and 42.5 ± 0.3% for 5 and 15 wt.% PLZT + 1 wt.% SiC, respectively, when compared to the aluminium alloy matrix.
