ACOUSTIC MICROSCOPY TECHNIQUES FOR OBSERVING DISLOCATION DAMPING

Abstract
A unique advantage of scanning acoustic microscopy lies in the ability to image the interaction of acoustic waves with a specimen. This can be made quantitative, so that the velocity and attenuation of surface waves can be measured over a few microns. This technique can be applied to the detection of dislocation damping in the acoustic microscope.
