Abstract

Current paper describes an application of laser ultrasonic time-of-flight measurement method for estimation of local density of pure tungsten sample. Formulas for estimation of density from speed of sound are derived. Experimental maps of sample density are presented. Accuracy of estimations is up to 37 kg/m 3.
