Design, Fabrication, and Properties of High Damping Metal Matrix Composites—A Review

Abstract

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.

Study of damping capacity of Fe–5.4Al–0.05Ti alloy

“…There is a growing demand for the development of damping materials that have high damping capacity as well as high strength, especially for home appliances, automobile, warship, and seismic applications to reduce unwanted noise and vibration [1,2]. High damping metals, often abbreviated as "Hidamets" or HDM, as a group of smart materials play an important role in both active and passive control of vibration and noise [3e5].…”

High damping NiTi/Ti3Sn in situ composite with transformation-mediated plasticity

“…High damping materials are used in various fields to eliminate noise, to reduce mechanical vibration, and to protect buildings against earthquake [1][2][3][4][5][6][7]. The combination of high damping capacity and good mechanical properties is very important for structural applications.…”

“…The combination of high damping capacity and good mechanical properties is very important for structural applications. However, these properties are often incompatible in metals, because of the trade-off relations between strength and damping [1,2]. Therefore, it is of interest to search and develop new damping materials that can simultaneously couple high damping capacity and excellent mechanical performances.…”

Novel Ti3Sn based high damping material with high strength

“…[1][2][3] High damping materials can convert the mechanical energy of vibration into heat, thus eliminating noise and vibration effectively, and are finding increasing applications in mechanical structures. [3][4][5] Apart from thermoelastic damping, the majority of damping mechanisms in metallic materials relate to the stressn induced movement of crystalline defects.…”
