Douglass, D L

The method of ultrasonic determination of uranium grain size consists of introducing a beam of ultrasound y means of a quartz transducer. The same transducer serves both to send a ngth of the sound to the grain size is less than 10:1, sufficient rains to yield a quantitative estimate of grain size. To apply the method to a specific material, the frequency of the Rened back red plotted against the actual grain size, determined metallographically, to give a calibration curve. Alpha-rolled uranium, having an average grain size of about 60 mu sshowed twelve or more back reflections, whereas betatreated uranium showed one or two back reflections. The test is sensitive to variation of sample thickness; therefore, the calibration curve was determined for specimens havfng the same thickness 180 mils. (auth)
