Ultrasonic research and applications in the NIST manufacturing engineering laboratory

摘要

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 emis- sion 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.
