Ultrasonic Attenuation in Solid Helium

A great deal of information about the motion of dislocations in solid helium has been obtained from ultrasonic and interna1 friction measurements. A brief review is given and representative data for 3 ~ e are presented, showing dislocation resonance and damping as well as pinning effects.

Attenuation of ultrasonic waves in rolled metals.

Scattering of ultrasonic waves in polycrystals with texture is studied in this article. The attenuations of the three wave modes are determined as a function of dimensionless frequency and propagation direction, respectively, for given orientation distribution coefficients (ODCs). The calculation is done in the case of a statistically orthorhombic sample made up of cubic crystallites. The wave ...
