Simulations of surface Brillouin scattering (SBS) spectra of TiC hard films on several substrates have been carried out over a range of film thickness from 5 nm to 1000 nm. The simulations are based on the elastodynamic Green’s function method that

Surface Brillouin scattering of light allows the angular-dependent velocities of Rayleigh surface acoustic waves (SAW), pseudo-SAW and longitudinal lateral waves (L) on the surface of an opaque crystal to be measured, and the elastic constants thereb

Polycrystalline diamond (PCD) cylindrical tool-bits used in oil well drilling are susceptible to fracture due to the hostile environment of randomly occurring high impact loads. These tool-bits generally comprise of a PCD layer sintered onto a Co-cem
