“…As a result, the size of C 1 and C 2 can be used to determine the damping performance of an alloy; the larger C 1 and smaller C 2 , the greater the damping performance. 26 Table 1 displays the values of C 1 and C 2 obtained by fitting the G–L curves.…”

“…This may indicate that high damping magnesium alloys are substantially more sensitive to changes in amplitude than other magnesium alloys with typical damping capacities. 26,32 This could be as a result of poor solubility of Si, which leaves nearly no Si solute atoms in the matrix. The strain-amplitude-independent damping stage is explained by the interaction of dislocations and solute atoms.…”

The effects of Si content and solution heat treatment on the microstructure and damping properties of as-cast Mg–Si hypoeutectic alloys were investigated. Si has the capacity to refine grains of pure magnesium. The three contents of Mg–Si hypoeutectic alloys are all high-damping alloys. The damping value of the as-cast Mg–0.5 wt-%Si alloy was higher than that of the Mg–0.3 wt-%Si and Mg–0.8 wt-%Si alloys in the small strain amplitude area. Compared to the as-cast state, the solution heat-treated Mg–Si hypoeutectic alloys show an increase in damping values, which are close to each other for the three contents in the small strain amplitude area, and decrease with increasing Si content in the high strain amplitude area as in the as-cast state.

“…Under high strain amplitude, the damping performance of the sample parallel to the extrusion direction is the best. Yan et al [84] found that Mg-0.6Zr sheets rolled at high strain rates possess higher damping properties. The dynamically recrystallized grains rotate to weaken the preferred direction of the basal texture, resulting in a weaker basal texture [85].…”

Magnesium alloys with high damping, high specific strength and low density have attracted great attention in recent years. However, the application of magnesium alloys is limited by the balance between their mechanical and damping properties. The strength and plasticity of magnesium alloys with high damping performance often cannot meet the industrial requirements. Understanding the damping mechanism of magnesium alloys is significant for developing new materials with high damping and mechanical properties. In this paper, the damping mechanisms and internal factors of the damping properties of magnesium alloys are comprehensively reviewed. Some damping mechanisms have been studied by many scholars, and it has been found that they can be used to explain damping performance. Among existing damping mechanisms, the G-L dislocation theory, twin damping mechanism and interface damping mechanism are considered common. In addition, some specific long-period stacking ordered (LPSO) phases’ crystal structures are conducive to dislocation movement, which is good for improving damping performance. Usually, the damping properties of magnesium alloys are affected by some internal factors directly, such as dislocation density, solute atoms, grain texture and boundaries, etc. These internal factors affect damping performance by influencing the dissipation of energy within the crystal. Scholars are working to find novel damping mechanisms and suitable solute atoms that can improve damping performance. It is important to understand the main damping mechanisms and the internal factors for guiding the development of novel high-damping magnesium alloys.

“…The system damping [32] during the vibration of the cantilever beam mainly derives from two aspects: one is the air viscoelastic damping [33], during the vibration of piezoelectric oscillators, which can be expressed by viscoelastic damping coefficient ξ a and the other is strain rate damping [34] during the vibration of piezoelectric oscillators, which can be expressed by strain rate damping coefficient ξ s . Both of the above damping satisfy the proportional damping criterion [31,35].…”

In micron or nano smart sensing systems, piezoelectric cantilever beams are distributed as major components in microsensors, actuators, and energy harvesters. This paper investigates the performance of four cantilever beam devices with “electric-force” conversion based on the inverse piezoelectric effect of lithium niobate (LiNbO3, LN) single-crystal materials. A new compact piezoelectric smart device model is proposed, designed as a single mass block connected by four beams, where devices exhibit smaller lateral errors (0.39–0.41%). The relationship between the displacement characteristics of cantilever beams and driving voltage was researched by applying excitation signals. The results show that the device has the maximum displacement at a first-order intrinsic frequency (fosc = 11.338 kHz), while the displacement shows a good linear relationship (R2 = 0.998) with driving voltage. The square wave signals of the same amplitude have greater “electrical-force” conversion efficiency. The output displacement can reach 12 nm, which is much higher than the output displacement with sinusoidal excitation. In addition, the relative displacement deviation of devices can be maintained within ±1% under multiple cycles of electrical signal loading. The small size, high reliability, and ultra-stability of Si–LN ferroelectric single-crystal cantilever beam devices with lower vibration amplitudes are promising for nanopositioning techniques in microscopy, diagnostics, and high-precision manufacturing applications.
