“…The amplitude dependence of the internal friction of the 18Cr-10Ni stainless steel [41] is qualitatively analogous to the same dependences for copper. Especially high values of the background are observed after annealing at 650°C (Fig.…”

High defect concentration and non-equilibrium state of nanocrystalline materials can lead to considerable increase of damping capacity, thus the investigation of dumping of the nanocrystalline metals produced by severe plastic deformation is of high importance nowadays. In this review, the latest achievements on the studying of the damping and structure of nanocrystalline materials are discussed for different metals and alloys. The results for amplitude and temperature dependences on internal friction for nanocrystalline metals and alloys prepared by different methods are presented. The results received for amplitude dependence of internal friction are analyzed in the connection with the mechanisms of dissipation of grain and grain boundary dislocations. The comparison of Bordoni, Snoek-Koster and grain boundary peaks, which were found on the temperature dependence of the internal friction is presented for metals in two states: nanocrystalline and coarse grained. After a brief overview of the production of nanocrystaline materials, the focus is set on the damping and structure as well as some mechanical properties of these materials. Both experimental and theoretical investigations of damping capacity in connection with strength properties together with some typical examples are presented. Open issues in the development of nanocrystalline materials with high internal friction are discussed in the conclusion section.

“…Because the damping properties in the stainless steel subjected to deformation and temperature, the maximum damping loss factor is not bigger than 0.01 [30], and the damping loss factor of 304SS is assumed to be 0.005. In order to investigate the effects of breathing behaviour on the dynamic response and the crack growth, the mode frequency, friction damping loss factor, dynamic stress, dynamic stress intensity, and crack growth are analyzed.…”

The effects of breathing behaviour on the dynamic response and crack growth are studied through a cracked cantilever beam. The main goal is to reveal the coupling mechanism of dynamic response and crack growth by employing a plain single-degreeof-freedom (SDOF) lumped system with the breathing crack stiffness and friction damping. The friction damping loss factor is derived by using Coulomb friction model and energy principle. Natural frequency, dynamic stress, dynamic stress intensity factor (DSIF), and crack growth are analyzed by case studies in the end. Results indicate that not only does the stiffness oscillates during crack growth corresponding to the physically open and closed states of the crack, but also stiffness and friction damping oscillate nonlinearly with crack growth. This behaviour induces not only nonlinear dynamic response but also nonlinear crack growth. It provides an approximate description of the nonlinearities introduced by the presence of a breathing crack. Therefore, it can be employed to improve the prediction precision of the crack identification and crack growth life of a cracked cantilever beam.

The results of a study of the structure of submicrocrystalline metals conducted with the help of transmission electron microscopy, MiJssbauer spectroscopy, and calorimetric measurements are presented. The effect of the special features of the microstructure on the amplitude and temperature dependences of the internal friction in submicrocrystalline copper and steel 12Kh 18N I 0T is estimated.In recent years physicists and materials technologists have devoted much attention to new materials with ultrafine grains [1][2][3][4]. Such are nanocrystalline alloys with a mean grain size of about 10 nm and submicrocrystalline (SMC) alloys with a mean grain size of about 100 nm. The great interest in ultrafinegrained alloys is due to the fact that their physical properties differ quite substantially from those of conventional materials with coarser grains. This opens new possibilities in the creation of materials with unique combinations of properties.The internal friction is a very important property of metallic materials and has a theoretical and practical significance [5 -7]. The problem of damping the vibrations of materials has to be solved in industry and in transport. However, the use of traditional methods for manufacturing high-damping materials (correction of the composition of the alloy, use of alloys with magnetomechanical energy dissipation, etc.) diminishes their strength properties [7].We devoted the present study to the structure of SMC metals (Cu, Co, Fe, Ni, Pd) and the internal friction of SMC copper and corrosion-resistant steel 12Kh 18N 10T (_< 0.12% C, 17 -19% Cr, 9 -11% Ni, 0.4 -0.7% Ti, < 2% Mn, _< 0.8% Si).The SMC structure in the studied specimens has been formed by various methods. The metal prelbrms were subjected to an intense plastic deformation by the method of equichannel angular pressing [8] and to torsion under a quasihydrostatic pressure [9,4], and the steel preforms were subjected to all-sided forging. In the treatment by the first two methods the deformation was conducted to a true logarithmic degree e = 4 -7.I lhe results of the xx ork haxc been reported at the international con l'crence "Interaclion of Dcl;.'cts and Inelastic Phenomena in Solid Bodie~,'" that took -, place in Scptember 23 25, 1907, inlula.-Institute of Problem~, of Supcrplaslicitx ol'Metals, t'lh. t,',u>+ia.The SMC structure of the metals was studied by the methods of electron microscopic M~ssbauer and calorimetric analyses.An x-ray diffraction study [4,8,10] with the help of a JEM 2000 EX transmission electron microscope has shown that the intense plastic deformation of the metals (Cu, Co, Fe, Ni, Pd) provides a homogeneous grain structure where the grains (with a mean size d= 0.1 -0.2 !am) have nonequilibrium boundaries (Fig. la ). The nonequilibrium nature of the boundaries is confirmed by the diffusion contrast observed on the electron microscopic images and by the bent extinction contours in the grains that appear in the presence of longrange fields of internal stresses for which the grain boundaries are obviousl...
