Damping Capacity of Fe-Ga Alloys
Advanced Materials Research, 2011 The damping capacity of Fe-Ga rods and sheets has been studied using a computer-controlled automatic inverted torsion pendulum instruments in a wide temperature range in a series of frequency. The frequency and temperature has different influence on the damping capacity of solidified Fe83Ga17 rods and (Fe83Ga17)97.25Cr2B0.75 sheets.

Damping Capacity of Turning Tools, Part 2: Mechanism Initiating the Damping Capacity
Journal of Engineering for Industry, 1993This paper examines the mechanism initiating the damping capacity of a turning tool. The turning tool is considered as a beam on an elastic foundation. Parameters of the model are estimated from the experimental result of the free damped vibration frequency.

Higher Damping Capacities in Gradient Nanograined Metals
Nano Letters, 2022The capability of damping mechanical energy in polycrystalline metals depends on the activities of defects such as dislocation and grain boundary (GB). However, operating defects has the opposite effect on strength and damping capacity. In the quest for high damping metals, maintaining the level of strength is desirable in practice.

Damping capacity of nanotwinned copper
Acta Materialia, 2008Abstract Copper with different twin densities was obtained by its deposition from the vapour phase in the form of coatings or separated condensates (foils) on substrates kept at different temperatures. True values of the logarithmic decrement (LD) for copper were calculated from LD amplitude dependences, measured for the coating–substrate system in ...

The damping capacity of a multilayer steel
Strength of Materials, 1994Damping capacities have been compared for multilayer steel specimens (substrate steel AK), which have various strengths in the joints between the layers and various dispositions of the joint zones relative to the surface; a multilayer steel containing a cobalt-base foil has also been examined. With that steel, there is a direct relationship between the

Development of NiTiNb in-situ composite with high damping capacity and high yield strength
Progress in Natural Science: Materials International, 2011 The shape memory alloys are well known to exhibit high damping capacity in martensite state, but possess low yield strength because of the reorientation or de-twining of the martensite variants.

Damping capacity of layered materials
Journal of Applied Physics, 1994Extensive measurements of the internal friction in a variety of layered materials such as graphite, metal dichalcogenides (MoS2, TiS2, NbSe2, TaS2, TaSe2, and TaTe2), and montmorillonite clays are reported. The internal friction of these layered materials exhibits features similar to those observed in graphite.
