Ultrasonic attenuation due to phonon-phonon interaction and thermo elastic mechanism have been evaluated in NbO along (110) direction in the temperature range 100-500K. The second and third order elastic constants are also evaluated for the evaluation of ultrasonic attenuation and other associated parameters. The ultrasonic attenuation due to phonon-phonon interaction is predominant over thermo elastic loss in this material. The results are discussed in correlation with thermo elastic properties of NbO.

AbstractThe ultrasonic study results for dependence of the elastic wave velocities and second-order elasticity coefficients of the polycrystalline aluminum alloy AMg6 and its nanocomposite n -AMg6/C_60 on hydrostatic pressure up to 1.6 GPa have been described. The ultrasonic research has been carried out using a highpressure ultrasonic piezometer based on the piston-cylinder device. The pressure derivatives of the secondorder elastic constants of these materials established in the present study have been compared with the results of the third-order elastic constants measurements of the test alloys using the Thurston–Brugger method. Involving available literature data, we determined the relationships between the pressure derivatives of the second-order elastic constants of the AMg6 alloy and the Mg-content and nanostructuring.

The structural and elastic properties of some alkaline earth mono-sulphide (AES: AE = Ca, Ba, Sr) under pressure have been investigated using a two body inter ionic potential approach with modified ionic charge (Zme). The phase transition pressures 39.9 GPa, 17.1 GPa, and 7.2GPa along with volume collapses 6%, 8.5% and 10.8% for CaS, SrS and BaS obtained by this approach, respectively and compared them with experimental measured data reveal good agreement. We have also calculated bulk modulus, pressure derivatives, second order (C11, C12& C44) and third order elastic constants (C111, C112, C123etc.) in NaCl (B1) phase which show predominantly ionic nature of these compounds.Keywords: High pressure behavior, equation of state, structural phase transition, second order elastic constants, third order elastic constants.
