Abstract:

This project involved the use of innovative acoustic techniques to study new materials and new developments in solid state physics. Major accomplishments include a the preparation and publication of a number of papers and book chapters, b the measurement and analysis of an aluminum alloy quasi-crystal and its cubic approximant c the use of resonant ultrasound to measure acoustic attenuation and determine the effects of heat treatment on ceramics, d the extension of our technique for measuring even lower possibly the lowest infrared optical absorption coefficient, and e the measurement of the effects of disorder on the propagation of a nonlinear pulse, and f the observation of statistical effects in measurements of individual bond breaking events in fracture.
