Measurements of the temperature dependence of the internal friction and frequency of three nanocrystalline diamond films grown on silicon oscillator substrates indicate that the mechanical properties of the films are dominated by their interface layers. The films, with thicknesses of 0.3, 0.6, and 1.14 μm, were measured between 0.4 K and room temperature and have low temperature (below 10 K) internal frictions between 2×10-6 and 5×10-6, which is an order of magnitude lower than has been reported previously. Additionally, all films display an internal friction peak at approximately 1.7 K. The shear modulus of the films, 545–551 GPa, is comparable to that for single-crystal diamond.

    Ultrasonic attenuation values of metals deduced using conventional pulse/echo methods contain contributions from both grain scattering and energy absorption (arising from internal friction). In contrast, the energy loss mechanisms, which contribute to diffuse field measurements, are believed to...

    The aim of the present study was to assess the influence of the angle of internal friction on the embedment depth with reference to cantilever sheet piles in cohesionless soils. Two design approaches were employed towards this end, namely the conventional CECP2 method and the limit state design...

    There is a well-known pattern of flaking failure under spherical ball-on-plate contact, i.e., the network between multiple Hertzian cracks causes the surface layer's separations. Based on this pattern previous researchers studied the failures of silicon nitride bearings. However, contrary to...

    The crystallization of amorphous silicon (a-Si) was achieved by field-aided lateral crystallization (FALC). Under the influence of an electric field, Cu is found to drastically enhance the lateral crystallization velocity of a-Si. When an electric field of 30 V/cm was applied to selectively...

    An unusually high damping peak of 20% has been observed in Ni52Mn24Ga24 single crystals accompanying with martensitic transformation. The high damping capacity can be retained in the low-temperature martensite phase when a bias field of 0.4 T was applied along the measurement direction. The...

    We discuss the stick-slip motion of an elastic block sliding along a rigid substrate. We argue that for a given external shear stress this system shows a discontinuous nonequilibrium transition from a uniform stick state to uniform sliding at some critical stress which is nothing but the...
