ULTRASONIC SPECTROSCOPY

Abstract

Various experimental difficulties discussed in the report had to be overcome to be able to adopt spectroscopic procedures for ultrasonic testing and to construct an ultrasonic spectroscope. The ultrasonic pulse-echo spectroscope recently developed and its practical use for nondestructive inspection purposes are described. Test results obtained with the instrument indicate its usefulness for determining defect characteristics which cannot be revealed by conventional ultrasonic test methods. In addition, it is shown how the ultrasonic spectroscope can be used to distinguish microstructures of steel specimens.
