Transit Times and the Elastic Properties and Debye Temperature of Some Selected Materials

This paper provides an introduction to the technology and procedures
pertinent to calculate the transit time of a ultrasonic wave in a solid state material. The technique is applied to two types of layered ternary carbides.


I. Introduction
Methods that employ the use of ultrasonic sound waves permits us to ¡§see through¡¨ opaque materials. As early as the 19th century, people in many different fields utilized the information provided by an object¡¦s resonance. During the industrial revolution, comparing the resonance of manufactured parts improved the steel smelting process [1]. The timbre from a musical instrument is depended on the quality of the material used to make it [2]. In the field of physics, the resonance spectra of any solid state material is depended upon the physical composition [3]. The benefit of using ultrasonic techniques is that it offers a nondestructive method in researching structural integrity.
The goal of this report is show how to ...
