Effect of thermal cycling on the damping behavior in alumina borate whisker with and without Bi2O3 coating reinforced pure aluminum composites

Effect of surface modified silicon carbide particles with Al2O3 and nanocrystalline spinel ZnAl2O4 on mechanical and damping properties of the composite

“…10(c and d). The damping behavior of the composites is intensively depends upon lattice defects (point defects, dislocations, grain boundaries and interfaces between reinforcements and matrix) [32,33,41].…”

“…Composite materials having high stiffness, better damping capacity and mechanical properties are extremely desirable in automobile, aerospace, construction and other industries where structural elements are exposed to dynamic loads [30][31][32][33][34][35]. In our proof-of-concept studies, we presented the results of an investigation on Al 2 O 3 and ZnAl 2 O 4 coatings on SiC particles of submicron size with very soft and simple techniques like sol gel method.…”

Effect of surface modification on silicon carbide particles with nanocrystalline spinel LZO for enhanced damping and mechanical property

“…Dislocation damping of the matrix and intrinsic damping of the reinforcement play a dominant role at relatively low temperatures. At higher temperatures, the sliding of interface and grain boundary is responsible for a large portion of the observed damping [45]. Granato-Lucke dislocation theory [46] plays significant role for explaining the dislocation motion between the matrix and the reinforcements.…”

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

“…An alloy ingot (7 >99.8 wt.%) by vacuum induction melting. Test samples cut from the ingot were annealed in vacuum at 950°C for 10 h. The microstructure of the composite ingot was characterized by means of X-ray diffraction (XRD, Bruker AXS D8 instrument) and scanning electron microscopy (SEM, FEI Quanta 200F instrument).…”

“…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.…”
