Abstract

The Ultrasonics Group in the NIST Manufacturing Engineering Laboratory performs research, develops standards, and offers calibration services in support of U.S. industry. Pulsed ultrasonic and acoustic emission techniques are pursued for application to materials nondestructive testing, medical diagnostics, and in-situ sensing of manufacturing processes. Associated analytic studies are made of the generation, propagation, and detection of ultrasonic pulses in liquids and solids. In this paper two areas of recent experimental research are summarized: (1) the development and application of a large aperture lensless line-focus transducer, and (2) the measurement of nonlinear wave propagation effects which are present in industrial ultrasonic nondestructive testing.
