Abstract : Ultrasonic inspection of the Tungsten Round Robin billets (Phase I) was completed. Tests conducted were primarily to determine: (1) best transducer frequency, (2) method of waterproof wrapping of uninfiltrated billets for immersed inspection, (3) velocity of sound measurements to detect density variations, and (4) detection of internal defects by both longitudinal and shear waves.
