Ultrasonic determination of carbon content in uranium metal

Abstract

A nondestructive method to determine solute content of carbon in polycrystalline uranium by ultrasonic techniques is currently being developed. The problem is approached by considering first theories developed in the field of physical acoustics applicable to variation in attenuation and elasticity with respect to interstitial and second-phase contents. Attention is given to the physical metallurgy of uranium, specifically phase stability and the effects of carbon concentration on physical properties. Experimental verification of theory is provided using Resonant Ultrasound Spectroscopy (RUS) and pulse-echo time of flight measurements, the former yielding elastic moduli and quality factors and the latter supplying attenuation and velocity information.
